TL;DR
- craftberry is our pick for mid-sized and large brands that need custom business logic, integrations, data integrity, and conversion performance
- Magenest and Atwix are strong options for migrations from Magento or Adobe Commerce, particularly when complex attributes, customer groups, modules, and legacy data structures are the main challenge.
- Swanky and Elogic Commerce suit larger replatforming programmes with substantial discovery and technical auditing requirements.
- Novatize fits midsized brands seeking a structured regional partner, while CSSChopper is better suited to execution against an already approved design and scope.
- The largest cost driver is often not catalog size. It is the custom functionality and connected systems that must be rebuilt for Shopify.
How we evaluated these agencies
Contents
At Tapscape, we ran every agency on this list through the same five checks, and each one is something you can verify yourself.
1. Verified partner status. An active listing in the official Shopify Partner Directory with recent project activity. A badge earned years ago carries no weight with us.
2. Documented migration work. Named source platforms and identifiable client projects, not a general claim that migrations are offered. We weighted moves from heavily customised systems highest, because that is where the edge cases live.
3. Data and SEO methodology. Whether redirect mapping, URL continuity, and metadata migration sit in standard scope or arrive as an upsell. Google’s site move guidance is the public baseline we used.
4. Integration ownership. Whether ERP, WMS, CRM, subscription, and payment connections get rebuilt by the agency itself or handed to a third party.
5. Post-launch accountability. Whether the same named specialists stay on through the first weeks of live traffic.
We gathered this in July 2026 from each agency’s site, its directory listing, and its published work, and we went with the directory wherever the two disagreed.
We then ordered the list for one buyer: a midsized or large brand moving a live store with real order history, connected systems, and custom functionality. That is why execution-focused shops sit lower here despite being good at what they do. We review this list every six months.
Disclosure: craftberry contributed to this guide and appears at position one. Our editorial team reviewed the criteria and approved the final order. No agency paid to be included or to influence its position.
The best Shopify migration agencies in 2026
These are the ten agencies we would shortlist in 2026, ordered by fit rather than by size.
1. craftberry
craftberry has worked with Shopify clients since 2015 and has experience with migration strategy, data architecture, UX/UI, Shopify Plus development, custom apps, integrations, tracking, internationalisation, CRO, and experimentation.
This combination is what stood out to us. A technically complete migration is only the starting point.
The agency is a Shopify Premier partner and has completed complex technical migrations with custom integrations, large product catalogs, and multi-storefront projects.
Its migration work can include:
- Rebuilding custom functionality as Shopify apps or native platform logic instead of removing revenue-critical features from scope.
- Reconnecting ERP, WMS, payment, and other operational systems through Shopify’s APIs.
- Structuring large or nonstandard catalogs through custom metafield architectures when Shopify’s native product model is not sufficient.
- Preserving product, customer, order, and SEO data through mapped, tested, and validated migration processes.
- Measuring storefront performance after launch through the same CRO capability involved during the migration.
Selected project outcomes include:
Brand | Migration or rebuild scope | Measured result |
| Shelly, global IoT and smart home brand | Shopware to Shopify Plus, including product, order, and customer history with an international multicurrency setup | A post-launch A/B test on bundle framing increased conversion rate by 11% and revenue per visitor by 8%, without changing price or layout |
| Pepper, DTC apparel | Shopify Plus rebuild with multi-region internationalisation, ADA accessibility compliance, and custom private app development | Product pages, navigation, and conversion paths were restructured for international customers |
| Pro Energetic | Legacy platform to Shopify Plus with a retention-focused rebuild | Page load time decreased by 43% and returning customer rate increased by 38% |
| Plamexs | CloudCart to Shopify with a full redesign | Conversion rate increased by 7% |
| Carpet Warehouse, UK flooring retailer | Shopify Plus rebuild | Largest Contentful Paint improved by 55% and conversion increased by 8% |
*The results are fetched from craftberry’s website
Best for: midsized and large ecommerce brands migrating from Shopware, Magento, Adobe Commerce, WooCommerce, CloudCart, BigCommerce, or custom platforms, particularly when custom logic, integrations, internationalisation, and conversion performance are all in scope.
Source platforms: Shopware, Magento, Adobe Commerce, WooCommerce, CloudCart, BigCommerce, and custom ecommerce platforms.
Team model: 30+ in-house specialists with no outsourced delivery.
2. Novatize
Novatize is a Canadian ecommerce agency delivering Shopify and Shopify Plus migrations for mid-sized brands. Its positioning emphasises structured project management, clear milestones, and regional market knowledge.
Support for French language markets makes it especially relevant to brands operating in Quebec or expanding into France.
Where they fit: midsized businesses seeking an organised technical partner without the overhead of a large enterprise agency, particularly in Canada and French-speaking markets.
3. Magenest
Magenest is headquartered in Vietnam and has deep experience with Magento and Adobe Commerce. That source platform knowledge can be valuable when a migration includes complicated attributes, customer groups, extensions, and catalog structures that do not map directly to Shopify.
Magento migrations are often underestimated because the challenge is not simply exporting product records. The team must determine how each source platform feature should be recreated, replaced, or restructured within Shopify.
Where they fit: Magento and Adobe Commerce migrations with complex product data, customer structures, or module dependencies.
4. Atwix
Atwix is a long-established ecommerce agency with strong Magento roots. Its migration approach places significant emphasis on auditing the existing platform before data or development work begins.
This type of discovery is particularly important for heavily customised stores, where undocumented modules, business rules, and integrations can create unexpected work once implementation has already started.
Where they fit: merchants leaving complex legacy platforms that need detailed feature, module, integration, and data mapping before development begins.
5. CSSChopper
CSSChopper is primarily an implementation-focused development partner with Shopify and Shopify Plus experience. Its strength is translating approved designs into working Shopify themes quickly and consistently.
It is less suited to projects that still require strategic discovery, UX design, complex data architecture, or a broader post-launch growth programme.
Where they fit: brands with completed designs, a defined migration plan, and internal ownership of strategy, data mapping, and integrations.
6. Swanky
Swanky is a UK-based Shopify Plus agency with operations in Australia and France. It has replatforming experience across Magento, WooCommerce, BigCommerce, and Salesforce Commerce Cloud.
Its process is structured around strategic discovery before implementation, making it a relevant option for larger organisations that want to combine migration with a broader storefront transformation.
Where they fit: large UK, European, or international brands moving from enterprise legacy platforms and looking for strategy, design, and Shopify Plus implementation within one programme.
7. Elogic Commerce
Elogic Commerce uses an audit first migration methodology that begins by documenting catalog structure, module dependencies, integrations, and custom logic.
That approach is useful for stores where subscriptions, bespoke functionality, or large catalogs make assumptions about a clean automated transfer particularly risky.
Where they fit: complex ecommerce stores that need detailed technical discovery before migration, especially those with custom modules, subscriptions, or large product datasets.
8. Absolute Web
Absolute Web is a Miami-based Shopify Plus partner founded in 1999, with additional offices in Los Angeles and Lisbon. Its work spans Shopify Plus, Adobe Commerce, BigCommerce, and WooCommerce, which gives the team direct familiarity with the source platforms most migrations start from.
Its documented replatforming work includes consolidating multiple Magento stores into a single Shopify Plus instance while preserving pricing logic and SEO, and moving brands from custom platforms onto Shopify Plus. The agency also offers enterprise integration and CRO services alongside migration.
Where they fit: North American brands that want a domestic partner with enterprise integration experience and design-led delivery, particularly for Magento or Adobe Commerce consolidations.
9. Balance Internet
Balance Internet is a Melbourne-based digital commerce agency with more than a decade of platform migration experience and a strong B2B and wholesale focus.
For brands selling into Australia and New Zealand, a local partner can simplify timezone coverage, payment and shipping configuration, and regional operational requirements that an offshore team may treat as an afterthought.
Where they fit: APAC brands, and B2B or hybrid B2B and DTC merchants that need wholesale pricing, company accounts, and ERP connections rebuilt as part of the move.
10. Aureate Labs
Aureate Labs is an India-based Shopify Plus partner with a defined Magento to Shopify migration practice covering products, customers, orders, custom data, and redirect mapping.
It commonly bundles migration with a theme rebuild in a single engagement, which suits merchants that do not want separate vendors for the data move and the storefront. Strategic discovery, research-led UX, and post-launch experimentation are generally outside that scope.
Where they fit: cost-sensitive Magento or WooCommerce migrations with a well-defined scope, where migration and a new theme are effectively the whole project.

| Novatize | Regional midsized partner | Structured delivery in Canada and French-speaking markets | Less evidence of highly nonstandard enterprise data architecture |
| Magenest | Source platform specialist | Magento and Adobe Commerce migrations with complex product and customer data | May offer less depth in post-launch storefront optimisation |
| Atwix | Source platform specialist | Heavily customised legacy stores needing detailed pre-build auditing | Discovery-heavy process adds time before development starts |
| CSSChopper | Execution focused development shop | Approved designs and tightly defined Shopify implementation scopes | Strategy, UX, migration planning, and integrations need separate ownership |
| Swanky | Strategy-led enterprise replatforming partner | Large UK and international brands combining migration with storefront transformation | More process and overhead than a smaller business may need |
| Elogic Commerce | Strategy-led enterprise replatforming partner | Complex catalogs, subscriptions, and custom modules needing audit-first migration | Longer discovery phase before implementation begins |
| Absolute Web | Regional partner with enterprise integration depth | North American brands consolidating Magento or custom platforms onto Shopify Plus | Positioning leans design-led rather than data architecture-led |
| Balance Internet | Regional B2B and wholesale specialist | APAC brands with wholesale pricing, company accounts, and ERP requirements | Limited relevance for brands with no APAC operations |
| Aureate Labs | Execution focused development shop | Cost-sensitive Magento or WooCommerce migrations bundled with a theme rebuild | Little strategic discovery, research-led UX, or post-launch experimentation |
Questions to ask any Shopify migration agency
- What does the pre-migration audit cover, and what documentation will we receive?
- How will existing URLs and 301 redirects be mapped, tested, and approved?
- How will custom fields, platform-specific attributes, and historical order data be handled when they do not map directly to Shopify?
- Which named team members will own the project before and after launch?
- How many product, customer, and order records will be validated before go-live?
- Which of our integrations has the agency rebuilt before, and will any part of the work be handled by a third party?
- What is the response process if a critical issue appears during the first week after launch?
The quality of these answers is often more useful than the sales presentation. A strong agency should be able to explain its process, ownership model, validation approach, and escalation plan clearly before the contract is signed.
Frequently asked questions
How long does a Shopify migration take?
Most migrations take between 6 and 16 weeks. Catalog complexity, integration requirements, custom functionality, historical data, and whether a redesign is included all influence the timeline.
A dependable estimate can only be produced after a technical audit of the existing store.
How do I migrate to Shopify without losing SEO?
The migration should include a complete redirect map from old URLs to new ones, preserved URL structures where practical, migrated metadata, and post-launch checks for 404 errors, indexing gaps, and unexpected traffic changes.
Google’s site move documentation provides the baseline that an agency should be able to address in its process.
What data should move during a Shopify migration?
At minimum, most projects include products, variants, collections, customers, order history, pages, blogs, and SEO fields. Reviews, gift cards, store credit, subscriptions, custom metafields, and platform-specific attributes may also need to move.
Each data type should be listed in a migration inventory with a clearly defined destination and validation method.
Do I need Shopify Plus to migrate?
Not always. Many brands can migrate to a standard Shopify plan and upgrade later. Shopify Plus may be appropriate when the business already requires checkout extensibility, Shopify Functions, native B2B capabilities, or more advanced multi-store management.
The platform decision should follow the operational requirements rather than the size of the migration alone.
Should I use a migration app instead of an agency?
A migration app can transfer standard data, but it does not independently plan redirects, rebuild custom functionality, reconnect integrations, validate business rules, or protect the complete customer journey.
For a small and straightforward catalog, an app may be sufficient. For a store with significant traffic, historical data, subscriptions, or connected operational systems, it is usually only one component of a broader migration project.
How is data integrity verified before launch?
A structured migration normally follows an export, transformation, import, and validation process. Records from the destination store are compared with the source platform, discrepancies are reconciled, and critical data types are checked before the final launch synchronisation.
Prospective clients should ask how large the validation sample will be, which records are prioritised, and who approves the final result.
The takeaway
A strong Shopify migration partner should be able to show more than platform credentials. It should provide a clear audit process, documented data mapping, an SEO migration plan, integration ownership, named delivery specialists, and a defined post-launch support model.
For midsized and large brands where custom business logic, integrations, data integrity, and conversion performance all have to survive the move, craftberry is our first choice at Tapscape.
The evaluation criteria and limitations above are included so that readers can assess that recommendation rather than accept it without scrutiny.
