Disclosure: WEBDIGITA is featured in this guide as a spotlight recommendation for mid-market enterprise assessment rather than as a ranked agency. The eCommerce migration services page covers platform selection, OpenCart exit scoping and Magento migration for stores where catalogue complexity and B2B requirements justify the investment.
An OpenCart store should migrate to Magento / Adobe Commerce when three conditions are present: a product catalogue large enough (typically 10,000+ SKUs with complex attribute sets) that WooCommerce performance under load is a genuine concern; B2B requirements – per-account pricing, shared catalogues, credit management, multi-user company accounts – that exceed what WooCommerce plugins or Shopify B2B handle natively; and an ERP integration requirement where Magento’s native data model fits the integration architecture better than middleware-heavy alternatives. For OpenCart stores that do not meet these conditions, WooCommerce or Shopify are better destination platforms. Migrating to Magento because OpenCart is getting old is not sufficient justification for the cost and infrastructure commitment Magento requires.
- OpenCart to Magento / Adobe Commerce migration is the enterprise upgrade path for the minority of OpenCart stores – most should evaluate WooCommerce or Shopify first. The catalogue size, B2B complexity and ERP integration requirements determine the destination platform, not the age of the source
- UK market pricing for an OpenCart to Magento Open Source migration runs from approximately £18,000 for a mid-complexity store with standard data migration and a configured Magento theme, to £80,000+ for Adobe Commerce builds with B2B functionality, ERP integration and custom checkout workflows
- Adobe Commerce (the enterprise tier, formerly Magento Commerce) requires an Adobe licence that starts at approximately £20,000-£40,000 per year. Magento Open Source is the free tier – most mid-market UK merchants migrate to Open Source rather than Adobe Commerce unless B2B module requirements or Adobe’s support SLA justify the licence cost
When OpenCart should upgrade to Magento – and when it should not
| Requirement | Migrate to Magento / Adobe Commerce | Choose WooCommerce or Shopify instead |
|---|---|---|
| Catalogue scale | 10,000+ SKUs with complex configurable product attribute sets, multiple websites or storeviews, and layered navigation that must perform under concurrent trade buyer sessions | Under 10,000 SKUs with standard product types and no multi-store requirement – WooCommerce or Shopify handle this without Magento’s infrastructure overhead |
| B2B requirements | Per-account contract pricing from ERP, shared catalogues per account with different product visibility, multi-user company accounts with approval hierarchies, credit limit enforcement at checkout, PunchOut or EDI requirements | 2-5 flat pricing tiers with role-based discounts, standard trade account registration flow – WooCommerce with B2BWoo or Shopify B2B on Plus covers this without Magento |
| ERP integration | Real-time per-account pricing sync from ERP, complex product data governed by PIM, high-frequency stock updates across multiple warehouses, bi-directional order management between ERP and eCommerce | Scheduled batch pricing updates and standard stock sync – WooCommerce middleware or Shopify apps handle this reliably without Magento’s integration architecture |
| Multi-store | Multiple branded storefronts sharing a single product catalogue, multi-language and multi-currency with store-view-level pricing and content, channel-specific catalogues | Single storefront with optional multi-currency – Shopify Markets or WooCommerce with WPML covers standard multi-currency and multi-language without the operational overhead of Magento multi-store |
WEBDIGITA – Enterprise Platform Assessment
For OpenCart merchants who need to confirm whether Magento is the correct destination before committing budget to an agency engagement
WEBDIGITA’s platform assessment for OpenCart exits evaluates whether Magento, WooCommerce or Shopify is the correct migration destination before any platform-specific agency is briefed. The assessment covers catalogue scale and attribute complexity, B2B requirements against Magento’s native modules versus WooCommerce plugins and Shopify B2B, ERP integration architecture and total cost of ownership across platform options.
Where Magento is confirmed as the correct destination, migration scope covers data extraction and mapping, Magento Open Source configuration, URL redirect strategy, ERP integration and post-launch support. Pricing approximately 40% below the UK market average.
Offices: London, Reading, Birmingham | Starting price: Approximately 40% below UK market average

Agency profiles
1. iWeb
The UK’s leading Akeneo Gold Partner and Adobe Gold Adobe Commerce agency – for OpenCart merchants migrating to Magento where complex product data, PIM governance and trade or wholesale B2B requirements justify the enterprise platform
- Specialisms
- Adobe Commerce (Magento) development and migration, Akeneo PIM integration (Gold Partner), complex product data models, trade and wholesale B2B, ERP-driven commerce, enterprise platform migration, foodservice and automotive parts sectors
- Office Locations
- Stafford
- Team Size
- 51-200
- Notable Clients
- JCB, Raleigh Bikes, Selco, Science in Sport, MyMemory, Scruffs, British Heart Foundation
- Adobe Commerce Status
- Adobe Gold Solution Partner; Akeneo Gold Partner; 250+ Magento stores confirmed
Why choose iWeb
- UK’s leading Akeneo Gold Partner with 60+ PIM/PXM implementations – for OpenCart merchants where product data governance is required alongside the migration. Large attribute-heavy catalogues frequently have product data quality problems that a PIM implementation resolves at source rather than inheriting as Magento configuration debt
- Complex product data models and trade/wholesale Magento implementations confirmed for automotive parts, building materials and foodservice supply – sectors where OpenCart merchants operating at scale most commonly find WooCommerce insufficient and Magento is the architecturally correct destination
- Adobe Gold Partner status is the highest available UK partner credential for Adobe Commerce, confirming delivery capability at enterprise scale with Adobe’s own validation
Evidence sources: iweb.co.uk (Adobe Gold Partner confirmed, Akeneo Gold Partner confirmed, 60+ Akeneo implementations confirmed, JCB/Raleigh/Selco/Science in Sport named clients, trade and wholesale B2B Magento confirmed)
Ideal for
OpenCart merchants migrating to Magento where product data complexity requires PIM governance alongside the platform migration – and for trade, wholesale, automotive parts, building materials and foodservice OpenCart stores where iWeb’s sector-specific Magento evidence is directly relevant.
Think twice if
Your OpenCart migration does not justify the scale of an Adobe Gold Partner engagement. iWeb’s client base is enterprise – confirm whether your catalogue size, B2B complexity and budget sit within their typical project scope before investing time in discovery conversations.
2. On Tap
The longest-serving Magento Partner in the UK with eCommerce Awards finalist recognition in 2025 – for OpenCart merchants migrating to Magento who want a UK agency with established multi-year Magento delivery credentials
- Specialisms
- Magento / Adobe Commerce development and migration, B2C and B2B Magento, Hyva frontend, platform migration, UK eCommerce Awards finalist 2025 (Best B2C UX and Best Full-Service Agency), multi-channel solutions
- Office Locations
- Cheadle, Stockport (Greater Manchester)
- Team Size
- 51-100
- Notable Clients
- Available on request
- Adobe Commerce Status
- Adobe Solution Partner; Hyva Gold Partner; longest-serving Magento Partner in the UK
Why choose On Tap
- Longest-serving Magento Partner in the UK signals institutional knowledge covering Magento across versions, architectures and upgrade paths that agencies formed after 2015 do not have – directly relevant for OpenCart merchants where the store is old and the Magento destination needs to be built for longevity
- eCommerce Awards finalist 2025 (Best B2C UX in eCommerce and Best Full-Service eCommerce Agency) confirms current delivery quality rather than historical reputation – a Magento agency that is still winning industry recognition in 2025 is still delivering at the level the awards criteria require
- Hyva Gold Partner status is relevant for OpenCart to Magento migrations where frontend performance is a priority requirement – Hyva replaces Magento’s default frontend with a significantly faster stack that addresses the Core Web Vitals performance ceiling that standard Magento deployments hit
Evidence sources: ontapgroup.com (Magento Partner confirmed, longest-serving UK Magento Partner confirmed, eCommerce Awards finalist 2025 confirmed, Hyva Gold Partner confirmed, B2C and B2B Magento confirmed)
Ideal for
OpenCart merchants migrating to Magento in the North West who want a partner with the longest UK Magento track record and current awards recognition – particularly where Hyva frontend performance is a migration requirement alongside the data and B2B build.
Think twice if
You need a London-based agency for in-person project governance. On Tap is Stockport-based – strong remote delivery, different engagement model for clients who require regular in-person sessions during a complex migration project.
3. Aware Digital
UK Hyva Gold Magento partner with B2B eCommerce and Adobe Commerce specialisms – for OpenCart merchants migrating to Magento where frontend performance and B2B platform configuration are both in scope
- Specialisms
- Magento 2 / Adobe Commerce development and migration, Hyva frontend, B2B eCommerce on Magento, performance optimisation, Northern Digital Awards winner (Audio-Technica), rescue projects, bespoke integrations
- Office Locations
- UK
- Team Size
- 11-50
- Notable Clients
- Audio-Technica (Northern Digital Awards Best eCommerce Site winner)
- Adobe Commerce Status
- Adobe Commerce Partner; Hyva Gold Partner
Why choose Aware Digital
- Northern Digital Awards Best eCommerce Site winner for Audio-Technica confirms Magento delivery quality on a live trading electronics brand – the category of OpenCart merchant most likely to require Magento (complex product catalogue with technical specifications, B2B reseller channels, multi-currency) will recognise Audio-Technica as a relevant comparable
- Hyva Gold Partner alongside Adobe Commerce Partner means the migration destination can be built on Hyva’s modern frontend from day one – more efficient than a Luma build followed by a Hyva upgrade for OpenCart stores where Core Web Vitals performance is a migration requirement
- Rescue project experience is directly relevant for OpenCart merchants where a previous migration attempt has produced a technically compromised Magento installation that needs audit and remediation
Evidence sources: awaredigital.co.uk (Adobe Commerce and Magento 2 confirmed, Hyva Gold Partner confirmed, B2B eCommerce confirmed, Audio-Technica Northern Digital Awards case study confirmed, rescue projects confirmed)
Ideal for
OpenCart merchants migrating to Magento who want Hyva frontend performance built in from the start, B2B eCommerce configuration on Magento, or rescue and remediation of a technically compromised Magento installation that resulted from a previous migration attempt.
Think twice if
Your OpenCart migration primarily requires Adobe Commerce Gold-level certification and the largest enterprise delivery team. Aware’s confirmed work is at mid-market to upper-mid-market scale – for the highest certification tier, iWeb at position 1 is more concentrated.
4. Envisage Digital
Bournemouth agency with 10+ years in the Magento ecosystem and confirmed OpenCart migration in scope – for OpenCart merchants uncertain between WooCommerce and Magento as destination who want an agency with active credentials on both
- Specialisms
- Adobe Commerce / Magento 2 development and migration, OpenCart migration confirmed, Hyva frontend, WooCommerce migration, B2C and B2B eCommerce, eCommerce Awards Bronze 2025, 24/7 support
- Office Locations
- Bournemouth
- Team Size
- 11-50
- Notable Clients
- The Wetsuit Centre
- Adobe Commerce Status
- Adobe Bronze Solution Partner; WooCommerce Partner; Hyva confirmed
Why choose Envisage Digital
- 10-plus years in the Magento ecosystem and OpenCart migration explicitly confirmed in scope – the source platform familiarity and destination platform depth that OpenCart to Magento migrations require. Agencies that only know Magento have to learn OpenCart from documentation; Envisage’s multi-platform operation means OpenCart is familiar territory
- eCommerce Awards Bronze 2025 for a Hyva site confirms current-year Magento delivery at award standard – Hyva Gold certification validates that the frontend approach is certified alongside the recognition
- WooCommerce Partner alongside Adobe Bronze means Envisage can evaluate whether WooCommerce or Magento is the correct destination for the OpenCart store without a structural platform preference. For OpenCart merchants still uncertain about their destination platform, this is the most directly useful credential pairing on this list
Evidence sources: envisagedigital.co.uk (10+ years Magento confirmed, Adobe Bronze Solution Partner confirmed, WooCommerce Partner confirmed, OpenCart migration in scope confirmed, eCommerce Awards Bronze 2025 confirmed, 24/7 support confirmed)
Ideal for
OpenCart merchants uncertain whether Magento or WooCommerce is the correct destination who want an agency with current credentials on both – and for Bournemouth or South coast businesses who want in-person agency access for a complex migration project.
Think twice if
You need Adobe Gold Partner status or the largest Magento team scale for your enterprise migration. Envisage’s Adobe Bronze level and boutique team size is appropriate for mid-market Magento builds – enterprise Adobe Commerce engagements need agencies at Gold level.
5. IDS Logic
Leeds-based UK eCommerce agency with a dedicated OpenCart to Magento 2 migration service page – the most specific published OpenCart-to-Magento source confirmation of any UK agency on this list
- Specialisms
- OpenCart to Magento 2 migration, Magento 2 development, eCommerce platform migration, 18+ years UK eCommerce experience, multi-platform scope, data migration, SEO preservation
- Office Locations
- Morley, Leeds
- Team Size
- 51-200
- Notable Clients
- Available on request
- Adobe Commerce Status
- Magento 2 migration confirmed; multi-platform migration specialist
Why choose IDS Logic
- Dedicated OpenCart to Magento 2 migration service page with detailed scope description – the most specific published OpenCart source confirmation of any UK agency on this list. Their documentation covers the migration rationale (OpenCart’s limitations at scale), the specific OpenCart-to-Magento data mapping challenges and their migration process framework including QA and test procedures
- 18-plus years of UK eCommerce agency experience covers OpenCart across all versions from the early 2010s through current installations – relevant for OpenCart merchants where the source store is old enough to present version-specific migration challenges that agencies without pre-2015 OpenCart experience have not encountered
- Their OpenCart to Magento documentation explicitly addresses the business case – when the migration is justified rather than just describing what transfers. That context is more useful than a generic migration service listing
Evidence sources: idslogic.co.uk/opencart-to-magento-2-migration-services.php (dedicated OpenCart to Magento 2 page confirmed, migration process documentation confirmed, 18+ years confirmed, Leeds UK confirmed)
Ideal for
UK OpenCart merchants wanting the agency with the most specific published OpenCart to Magento 2 migration documentation and process framework – particularly older OpenCart installations where source-platform familiarity matters as much as Magento destination depth.
Think twice if
You need Adobe Gold or Silver Partner status as a procurement requirement, or named Magento client case studies at enterprise scale. IDS Logic’s OpenCart to Magento evidence is strongest on published methodology rather than named enterprise client outcomes.
6. ChilliApple
London and Kent multi-platform agency with confirmed Magento migration and multi-store experience – for OpenCart merchants migrating to Magento who want build and post-launch maintenance from the same 70-person team
- Specialisms
- Magento development and migration, multi-store Magento, WooCommerce, Shopify, PrestaShop, 70+ team, tiered maintenance contracts, 24/7 support, 95%+ renewal rate, AI-enabled features
- Office Locations
- London, Kent
- Team Size
- 70+ in-house
- Notable Clients
- Available on request; client testimonials reference Magento migrations and multi-store setups
- Adobe Commerce Status
- Magento migration confirmed; multi-platform development
Why choose ChilliApple
- Client testimonials specifically reference Magento migrations and multi-store setups – the multi-store capability is relevant for OpenCart merchants migrating to Magento where multi-storefront architecture is one of the primary justifications for choosing Magento over WooCommerce or Shopify
- Same-team model for Magento build and maintenance: Magento requires ongoing PHP updates, extension compatibility testing and security patching at higher frequency than Shopify. ChilliApple’s 95% renewal rate signals that the ongoing maintenance relationship works in practice
- London and Kent offices with a 70-person team provides in-person project access and parallel workstream capacity – data migration, Magento configuration, extension setup and ERP integration running simultaneously rather than sequentially
Evidence sources: chilliapple.co.uk (Magento migrations and multi-store confirmed in client testimonials, 70+ team confirmed, 95% renewal rate confirmed, London and Kent confirmed, 24/7 support confirmed)
Ideal for
OpenCart merchants migrating to Magento who want the migration and ongoing Magento maintenance managed by the same London-based team – where the 95% renewal rate and 70-person capacity are more important than the highest Adobe Partner badge.
Think twice if
You need Adobe Gold Partner status, named Magento enterprise client case studies at automotive, foodservice or trade distribution scale, or the deepest specialist Magento knowledge. ChilliApple’s strength is multi-platform breadth and retainer continuity.
7. Inviqa
London enterprise Magento agency with Missguided, Radley, Graze and PZ Cussons in their portfolio – for large OpenCart merchants migrating to Adobe Commerce where London presence and enterprise-scale delivery track record are requirements
- Specialisms
- Enterprise Adobe Commerce / Magento development and migration, complex enterprise deployments, retail and brand Magento, London base, UK and Germany offices
- Office Locations
- London (UK and Germany)
- Team Size
- 51-200
- Notable Clients
- Missguided, Radley, Graze, PZ Cussons, Dreams
- Adobe Commerce Status
- Adobe Commerce Partner; enterprise scale
Why choose Inviqa
- Missguided, Radley, Graze, PZ Cussons and Dreams as named clients confirm Adobe Commerce delivery at enterprise retail scale – the category most relevant to large OpenCart merchants considering Adobe Commerce as their migration destination
- London headquarters with UK and Germany offices provides in-person access for the discovery, stakeholder workshops and go-live support that enterprise Adobe Commerce migrations require
- Long-standing UK market leader in enterprise retail Magento, with institutional knowledge of Adobe Commerce’s architecture, upgrade history and enterprise module ecosystem from years of large-scale delivery
Evidence sources: inviqa.com (Adobe Commerce Partner confirmed, Missguided/Radley/Graze/PZ Cussons/Dreams named clients, London headquarters confirmed, enterprise Magento positioning confirmed)
Ideal for
Large OpenCart merchants migrating to Adobe Commerce (enterprise licence) where in-person London agency access and an enterprise retail client base comparable to Missguided, Radley or PZ Cussons validate the relevant delivery track record.
Think twice if
Your OpenCart migration is mid-market in scale. Inviqa’s client base is predominantly large enterprise retail – their engagement model, timeline and cost structure is calibrated for projects at that scale rather than mid-market OpenCart exits.
8. JH
Nottingham Magento agency with Casio and Sunspel as named clients and multiple UK eCommerce Awards – for UK OpenCart merchants migrating to Magento where award-validated delivery quality and B2C and B2B Magento experience are the shortlisting criteria
- Specialisms
- Magento / Adobe Commerce development, B2C and B2B Magento, platform migration, fully responsive Magento builds, UK eCommerce Awards, Nottingham base
- Office Locations
- Nottingham
- Team Size
- 11-50
- Notable Clients
- Casio, Sunspel
- Adobe Commerce Status
- Adobe Solution Partner; award-winning Magento confirmed
Why choose JH
- Casio and Sunspel as named clients confirm Magento delivery for consumer electronics and luxury fashion respectively – both sectors with complex product catalogues, international trading and brand-quality design requirements that mid-to-upper-market OpenCart merchants migrating to Magento will recognise as relevant comparable evidence
- Multiple UK eCommerce Awards confirms delivery quality at industry-recognised standard – award-validated builds have been evaluated against objective criteria by independent judges
- B2C and B2B Magento confirmed – the combination mid-market UK OpenCart merchants need when migrating to Magento to serve retail and trade channels on the same instance with different pricing and catalogue access per account type
Evidence sources: jhdigital.co.uk (Casio and Sunspel named clients confirmed, UK eCommerce Awards confirmed, B2C and B2B Magento confirmed, Nottingham confirmed)
Ideal for
Mid-market UK OpenCart merchants in consumer electronics, luxury goods, fashion or similar brand-led sectors migrating to Magento – where Casio and Sunspel as named clients and UK eCommerce Awards confirm the relevant delivery quality evidence.
Think twice if
Your OpenCart migration requires wholesale distribution, automotive parts, foodservice or trade sector-specific Magento experience. JH’s published client base is consumer brand-oriented – for trade distribution Magento, iWeb at position 1 is more relevant.
9. Fluid Commerce
Manchester award-winning Adobe Commerce agency with straight-talking B2C and B2B Magento delivery – for North West UK OpenCart merchants migrating to Magento where regional agency access and award-recognised Adobe Commerce work are the relevant criteria
- Specialisms
- Adobe Commerce / Magento development, B2C and B2B Magento, award-winning eCommerce, multi-channel solutions, South West and North West UK delivery
- Office Locations
- Manchester (North West and South West)
- Team Size
- 11-50
- Notable Clients
- Available on request
- Adobe Commerce Status
- Adobe Commerce Partner; award-winning Magento confirmed
Why choose Fluid Commerce
- Award-winning Magento agency with a straight-talking positioning – relevant for OpenCart merchants who have experienced the gap between agency pitch quality and delivery quality. Agencies that lead with directness rather than superlatives tend to scope more honestly
- B2C and B2B multi-channel Magento delivery confirmed – the combination that a significant portion of OpenCart merchants migrating to Magento need, where the B2B channel (trade accounts, tiered pricing) and B2C channel (retail customers) need to coexist on the same Magento instance
- North West and South West UK presence provides regional access for OpenCart merchants in Manchester, Liverpool, Bristol and surrounding areas preferring in-person agency relationships for a complex migration
Evidence sources: fluid.co.uk (Adobe Commerce Partner confirmed, award-winning Magento confirmed, B2C and B2B multi-channel confirmed, North West and South West UK confirmed)
Ideal for
North West UK OpenCart merchants migrating to Magento who want a regional Adobe Commerce Partner with direct agency access, B2C and B2B multi-channel Magento capability and a straight-talking engagement approach.
Think twice if
You need Adobe Gold Partner status, named enterprise clients at Missguided or PZ Cussons scale, or the specialist PIM-led product data governance that iWeb’s Akeneo partnership provides. Fluid’s confirmed positioning is mid-market rather than largest-scale enterprise.
Pre-migration checklist for OpenCart to Magento
- Confirm the platform choice before briefing any Magento agency. The Magento decision should be based on specific requirements: catalogue scale above 10,000 SKUs with complex attribute sets, B2B requirements beyond plugin capability, ERP integration architecture, or multi-store. Briefing a Magento agency without this analysis results in a scope that assumes Magento is correct rather than evaluating whether it is
- Decide between Magento Open Source and Adobe Commerce before discovery begins. Open Source is free; Adobe Commerce requires an annual licence from approximately £20,000-£40,000. B2B modules (shared catalogues, company accounts, purchase order approval) are native to Adobe Commerce and require third-party extensions on Open Source
- Map OpenCart product options to Magento configurable product architecture before data migration begins. OpenCart’s option system differs from Magento’s configurable product and attribute set model. Mapping decisions – which options become attribute sets, which become simple product variations – affect catalogue navigation, SEO URL structure and checkout behaviour
- Plan the hosting architecture before build begins. Magento requires dedicated or managed hosting, Redis or Varnish caching, Elasticsearch for catalogue search and PHP worker configuration – decisions that need to be made alongside the platform decision, not after go-live
Final thoughts
Most OpenCart stores should not migrate to Magento. WooCommerce or Shopify are the correct destination for the majority of OpenCart exits – lower total cost of ownership, easier to maintain, and adequate for the catalogue complexity and B2B requirements that most OpenCart stores actually have. Magento is the correct destination when catalogue scale, B2B module requirements, ERP integration architecture or multi-store complexity genuinely exceed what WooCommerce and Shopify can handle. Confirming which category applies before briefing any agency is the most valuable step in an OpenCart migration process.

Frequently asked questions
1. When does an OpenCart store need to upgrade to Magento / Adobe Commerce?
Three conditions need to be present simultaneously. First, a product catalogue large enough - typically 10,000+ SKUs with complex attribute sets - that WooCommerce performance under concurrent trade buyer sessions is a genuine concern. Second, B2B requirements that exceed what WooCommerce plugins or Shopify B2B handle natively: per-account contract pricing from ERP, shared catalogues per account with different product visibility, multi-user company accounts with approval hierarchies, or credit limit enforcement at checkout. Third, an ERP integration architecture where Magento's native data model is a better fit than middleware-heavy alternatives. Most OpenCart stores do not meet all three conditions. For those that do not, WooCommerce or Shopify are better destination platforms.
2. What is the difference between Magento Open Source and Adobe Commerce?
Magento Open Source is the free, community edition. It includes the core eCommerce platform with product catalogue, checkout, customer management, multi-store and SEO functionality. Adobe Commerce is the paid enterprise tier, formerly Magento Commerce, and requires an annual licence starting at approximately £20,000-£40,000 depending on revenue. Adobe Commerce includes native B2B modules - shared catalogues, company accounts, purchase order approval, quick order and requisition lists - that require third-party extensions on Magento Open Source. Most mid-market UK merchants migrating from OpenCart use Magento Open Source. Adobe Commerce is warranted when B2B module requirements, Adobe's enterprise support SLA, or integration with Adobe's marketing technology stack justify the licence cost.
3. How long does an OpenCart to Magento migration take?
A mid-complexity OpenCart to Magento migration - standard product catalogue, basic data migration, configured Magento theme, no ERP integration - typically runs ten to sixteen weeks. Complex migrations with B2B module configuration, ERP integration, Hyva frontend build and custom checkout workflows run twenty to thirty weeks. The most significant timeline variable is the extension audit and custom module development scope. Agencies that commit to timelines before completing the extension audit are estimating without the information that determines the actual project length.
4. How much does an OpenCart to Magento migration cost in the UK?
UK pricing for OpenCart to Magento Open Source migration runs from approximately £18,000 for a mid-complexity store with standard data migration and configured Magento theme, to £80,000-plus for builds with B2B module configuration, ERP integration, Hyva frontend and custom checkout workflows. Adobe Commerce builds add the annual licence cost (£20,000-£40,000+) to the build cost. WEBDIGITA's OpenCart to Magento migration pricing is approximately 40% below the UK market average for comparable scope.
5. What data migrates from OpenCart to Magento?
Standard migration scope covers products with descriptions, images and categories; product options mapped to Magento configurable products and attribute sets; customer records and customer groups; order history; CMS pages; reviews; and SEO URL redirects from OpenCart's URL structure to Magento's URL key system. OpenCart's extension functionality does not transfer - every extension needs a Magento extension equivalent identified and configured. Custom PHP code in OpenCart overrides requires rebuilding as Magento plugins or modules. Customer passwords require a reset on first login due to different hashing methods.
6. Should I migrate my OpenCart store to Magento or WooCommerce?
WooCommerce is the correct destination for the majority of OpenCart exits. Magento's total cost of ownership - hosting, developer retainer, extension licences and potentially Adobe Commerce licence - is higher than WooCommerce at standard complexity levels, and that premium is only justified when the platform capabilities Magento provides cannot be replicated on WooCommerce. Magento is the correct choice when catalogue scale exceeds 10,000 SKUs with complex attribute sets, B2B requirements include per-account contract pricing or multi-user company accounts, ERP integration requires Magento's native data model, or multi-store architecture with separate product visibility per storefront is a hard requirement. Run the platform assessment before briefing any Magento-specific agency.
