Best Shopify Migration Agencies for 2026: 7 Expert Partners for Seamless Platform Transitions

Moving your online store to Shopify Plus is one of the most consequential decisions you can make for your ecommerce business. Get it right, and you unlock faster page speeds, lower total cost of ownership, and a platform that processes over 10,000 orders per minute. Get it wrong, and a poorly executed migration can result in a 40% traffic loss, broken integrations, and corrupted customer data that takes months to recover from.

A Shopify migration agency handles the entire process of moving your existing store from one ecommerce platform to another. That means transferring products, customer accounts, and order history. It means rebuilding integrations with your ERP, WMS, and CRM. It means preserving the SEO rankings you've spent years building. And it means doing all of this without losing revenue or disrupting operations.

The complexity scales dramatically depending on your current platform. Magento stores often carry dozens of custom modules and B2B logic. WooCommerce sites may have messy data structures and plugin conflicts. Salesforce Commerce Cloud and custom platforms come with their own unique constraints. Each of these scenarios demands a migration team with specific platform expertise.

We evaluated the agencies below on migration methodology, data accuracy, SEO preservation, integration capabilities, post-launch support, and documented client results. Here are the seven best Shopify migration agencies for 2026.

How we chose the best Shopify migration agencies

Choosing a Shopify migration agency is a critical business decision, not something you should base on a flashy portfolio alone. Here's what we looked for:

• Migration methodology and data transfer processes. Agencies should provide a clear project plan with milestones, including defined phases from discovery through post-launch monitoring.
• Data integrity protection. Data integrity is crucial when moving thousands of products and customer profiles. We looked for agencies that validate every product variant, customer record, and order before and after migration.
• SEO preservation. A documented plan for URL mapping and redirects. Implementing 301 redirects is critical for maintaining search rankings.
• Integration rebuilding. We evaluated how agencies handle ERP, WMS, CRM, POS, and subscription system connections.
• Post-launch support. The best agencies don't disappear after go-live. We prioritized those with structured monitoring, bug-fix windows, and ongoing optimization options.
• Track record with complex migrations. Real case studies with measurable outcomes — conversion lifts, traffic retention, performance improvements — matter more than client logos.
• Transparent pricing and project management. Security and compliance measures matter in the migration process, and so does knowing what you're paying for.

Top 7 Shopify migration agencies for 2026

1. Solo Media Group

Solo Media Group is a full-service Shopify Platinum agency that combines brand-led design, custom development, and migration expertise across 75+ successful replatforms. Unlike agencies that treat migration as a purely technical exercise, we approach every store migration as an opportunity to elevate brand experience alongside platform performance.

Why it stands out. The key differentiator is end-to-end ownership. Rather than splitting design and development across separate vendors, we handle custom theme development, system integrations, data migration, SEO preservation, and retention marketing under one roof. This eliminates the coordination friction that plagues multi-vendor migrations.

Best for. Mid-market to enterprise D2C brands in beauty, wellness, food and beverage, and specialty retail seeking comprehensive replatforming that improves both the technical foundation and the customer-facing brand experience.

Key strengths

• Full-stack migration capability: design, development, integrations, data transfer, and post-launch retention marketing in a single partner
• Deep Shopify Plus expertise including POS, wholesale, and omnichannel setup — critical for brands with retail and B2B channels
• Brand-led approach ensures your new Shopify store isn't just a carbon copy of the old one, but a genuine upgrade in customer experience

Possible limitations

• Comprehensive scope means investment levels are aligned with mid-market and enterprise budgets, not starter projects
• Brands looking for a quick, template-based migration without design or strategy work may find the full-service model more than they need

2. Elogic Commerce

Elogic Commerce is an enterprise-focused agency with 89+ documented case studies spanning B2C and B2B migrations. Their audit-first migration approach means every project begins with deep technical discovery before a single line of code is written.

Why it stands out. Elogic's pre-migration auditing methodology sets them apart. They map every integration, data structure, and custom feature before proposing architecture. Most migrations require a pre-migration audit of the current store, and Elogic treats this as a non-negotiable first phase.

Best for. Complex, heavily customized stores with ERP integrations (SAP, NetSuite), B2B pricing logic, account hierarchies, or multi-market operations needing thorough analysis before execution.

Key strengths

• Zeus project: WooCommerce to Shopify Plus B2B migration with 12,000+ SKUs and SAP Business One ERP integration, achieving zero downtime
• Documented client results including revenue +17.3%, order volume +14%, and AOV +5.9% within six months
• Strong international migration capability, managing 47+ country launches with Shopify Markets Pro

Possible limitations

• Discovery phases can add time and cost upfront, sometimes revealing more scope than anticipated
• Requires significant internal readiness — clean product data, defined pricing rules, and SKU hygiene — before migration begins

3. Absolute Web

Absolute Web is a Miami-based agency with offices in LA and Lisbon, specializing in enterprise Shopify Plus migrations with a strong focus on performance optimization. They handle migrations from Magento, WooCommerce, BigCommerce, Salesforce Commerce Cloud, and custom platforms.

Why it stands out. Speed optimization and SEO preservation are baked into every migration. Absolute Web rebuilds stores with Core Web Vitals as a primary target, which matters because SEO rankings can improve post-migration due to faster page speeds. Their case studies demonstrate this performance-first philosophy.

Best for. Growth-stage DTC brands with established organic traffic that cannot afford search ranking drops during migration.

Key strengths

• Custom migrations including headless-to-native transitions and enterprise integrations for subscription and membership functionality
• Modloft migration from a custom platform to Shopify Plus delivered measurable UX and performance improvements
• Strong search engine optimization discipline, with redirect mapping that preserves SEO authority from old pages

Possible limitations

• High customization capability means costs and timelines skew higher than simpler migration services
• Smaller brands with straightforward B2C needs may find some offerings overbuilt for their requirements

4. We Make Websites

We Make Websites is a design-led, global Shopify Plus agency that has shipped 600+ store projects with an estimated £3B+ in client GMV under management. Their 95% client retention rate speaks to long-term partnership quality.

Why it stands out. Global brand migrations with B2B and wholesale complexity are where We Make Websites excels. They handle multi-currency, multi-market, and localized commerce workflows with the design polish that lifestyle brands demand.

Best for. International brands with multi-market requirements, especially those in fashion, beauty, and wellness that need design excellence alongside technical migration rigor.

Key strengths

• Deep experience with internationalization: currencies, taxes, shipping zones, and localized customer experiences across markets
• Discovery workshops that map business objectives to technical architecture before migration begins
• Exceptional UX and accessibility standards that go beyond just moving data to a new store

Possible limitations

• Very custom B2B pricing logic or large-scale ERP integrations may require pairing with a more technically specialized partner
• Design-forward approach commands premium fees that reflect the brand strategy investment

5. Swanky

Swanky is a UK-based Shopify Plus Expert partner with teams across the UK, Australia, and France. They specialize in complex platform migrations from legacy platforms including Magento, Adobe Commerce, and WordPress-based systems.

Why it stands out. Experience with deeply customized legacy systems — including Salesforce Commerce Cloud migrations and multi-brand retail environments — gives Swanky an edge when dealing with complex operations. Their Naturalmat migration from Adobe Commerce to Shopify Plus resulted in 56.4% revenue growth, while Kent Brushes saw revenue increase 67% and conversion rate improve 52% post-migration.

Best for. Enterprise brands migrating from heavily customized legacy platforms, particularly those with multi-brand portfolios or international market expansion plans.

Key strengths

• Proven track record with Magento to Shopify Plus migrations involving catalog restructuring, UX redesign, and performance optimization
• Multi-market expertise including DACH region compliance, tax localization, and currency management
• Strong conversion rate optimization baked into the migration, not bolted on afterward

Possible limitations

• UK/Europe headquarters may create time zone challenges for US-based teams needing real-time collaboration
• Premium design and localization work extends both timelines and budgets beyond simpler migration projects

6. Eastside Co

Eastside Co is a Shopify Plus Partner that focuses on mid-market brands seeking high-quality migrations without the overhead of enterprise-tier pricing. They've built a reputation for reliable ecommerce development and migration execution for growing D2C brands.

Why it stands out. Quality migrations at accessible price points for growing brands is their sweet spot. While many agencies optimize for enterprise budgets, Eastside Co delivers solid migration methodology to mid-market brands that are scaling but not yet at enterprise complexity.

Best for. Mid-size DTC brands upgrading from WooCommerce, Squarespace, or other platforms that need professional migration without enterprise-level investment. Shopify Plus migrations typically cost between $10,000 and $50,000, and Eastside Co tends to operate efficiently within the lower-to-mid range depending on scope.

Key strengths

• Streamlined migration process designed for mid-market catalogs and standard integration requirements
• Responsive project management with clear milestone communication throughout the setup process
• Capable theme implementation and custom theme work that balances quality with budget

Possible limitations

• May lack the capacity for very large-scale enterprise migrations with dozens of integrations or 100K+ SKU catalogs
• Brands needing advanced B2B features, headless commerce, or multi-market rollouts may require a more specialized partner

7. Blackbelt Commerce

Blackbelt Commerce is an NYC-based boutique Shopify Plus agency founded and managed by a father-daughter team. They've shipped 1,000+ stores and maintain a 98% renewal rate with 90% of business coming from referrals — metrics that reflect deep client trust.

Why it stands out. Enterprise-grade project management with boutique attention. Blackbelt Commerce emphasizes risk mitigation in every migration, noting that poorly executed migrations often cost brands a quarter of organic traffic on day one. Their founders personally oversee projects, which is rare at this level.

Best for. Enterprise brands and premium D2C companies with complex data structures and integrations that value personal oversight, craftsmanship, and long-term reliability over agency scale.

Key strengths

• Founder-led oversight ensures accountability that larger agencies struggle to replicate
• 178 five-star reviews and an industry-leading referral rate demonstrate consistent delivery quality
• Strong emphasis on protecting customer records, product variants, and SEO elements during every migration

Possible limitations

• Boutique scale means capacity constraints for simultaneous large-scale projects across multiple brands
• Pricing reflects the high-touch, founder-led model, which may be above market for simpler migration needs

How to choose the right Shopify migration agency

Choose based on your current platform

Platform-specific expertise can dramatically affect the success of a migration. Choose agencies with proven experience on your current platform, not just general Shopify knowledge.

• Magento / Adobe Commerce. These migrations are usually more expensive due to complexity. Custom modules, B2B logic, multi-store configurations, and legacy database structures all require careful data mapping and feature parity planning. Elogic, Swanky, and Solo Media Group all have strong Magento migration track records.
• WooCommerce. Data structures can be inconsistent due to plugin conflicts and uneven architecture. Look for agencies skilled in data cleanup and validation. Understanding what a Shopify agency actually does during these transitions helps set expectations.
• BigCommerce and Salesforce Commerce Cloud. These require careful URL structure mapping and feature translation to Shopify equivalents. Absolute Web has demonstrated experience here.
• Custom platforms. Legacy and custom-built stores often lack documentation and audit trails. A demo migration or proof-of-concept phase is worth requesting before committing to full scope.

Choose based on business size and complexity

Migration costs depend on catalog size and integration complexity. A brand with 500 SKUs and a single Klaviyo integration faces a fundamentally different migration than one with 50,000 SKUs, SAP ERP, custom B2B pricing, and POS across 12 locations.

Most migrations take 4 to 12 weeks to complete. Shopify Plus merchants see a 17% higher conversion rate on average, Plus includes unlimited staff accounts for better team management, and the platform offers advanced reporting not available in standard Shopify. These advantages compound faster for brands that plan their migration scope carefully.

What a migration actually costs

No neutral body publishes these rates, so every figure traces to an agency's own page.

Tier	Range	Timeline
Simple, catalog and theme port	$20,000 – $30,000	8–12 weeks
Mid-market, custom theme, light B2B, ERP	$30,000 – $60,000	12–18 weeks
Enterprise Plus rebuild	$75,000 – $150,000+	16–24 weeks

Choose based on post-launch support needs

Ensure the agency provides post-launch support and monitoring. Monitoring Google Search Console after launch is essential — you need to catch crawl errors, indexing issues, and redirect failures within the first 48 hours.

A successful migration involves five clear phases: discovery and audit, planning and architecture, development and data migration, QA and staging review, and launch with post-launch monitoring. The agencies that excel treat phase five as an ongoing engagement, not a checkbox.

Look for agencies with dedicated migration teams, not generalists who split their time across unrelated projects. Shopify Plus also provides dedicated account managers for support on the platform side, but your agency partner needs to be equally responsive in those critical first weeks.

Which migration agency is best for you?

Your ideal partner depends on where you're migrating from, what you're migrating with, and what you need after launch.

• Choose Solo Media Group if you want comprehensive replatforming that upgrades your brand experience alongside your technology. Our Shopify Plus migration services combine custom theme development, system integrations, data transfer, and growth marketing into a single engagement. If your current store looks and performs like it did in 2020, migration is your chance to fix both at once.
• Choose Elogic if you need the most rigorous data protection and audit processes. Ask for references from previous clients to verify performance before signing.
• Choose Absolute Web or We Make Websites if SEO preservation and international complexity are your priorities. 301 redirects are critical to preserve rankings during migration, and these agencies build redirect discipline into their standard workflow.
• Choose Eastside Co if you're a mid-market brand seeking quality work at reasonable investment levels, sized for growing brands rather than enterprise budgets.

Final thoughts

A successful Shopify migration depends on matching agency expertise to your specific platform, business size, and operational complexity. There's no single best agency — there's the best agency for your situation.

The Shopify platform offers enormous advantages once you're on it: speed, scalability, a thriving ecosystem of apps and integrations, and infrastructure that handles traffic spikes without server management headaches. But the migration process itself is where value is won or lost. A poorly executed migration can lead to significant traffic loss, corrupted customer data, and months of recovery. A well-executed one protects your revenue, improves your conversion rates, and sets up years of compounding growth.

Before committing, consult with at least two or three agencies. Ask about their migration tooling, how they handle customer passwords (Shopify requires password resets on migration), how they validate that every CSV and XML file imports correctly, and what their plan is for the first 30 days post-launch. Ask them to walk you through a past project that mirrors yours — migrated correctly, on time, with search rankings intact.

Proper migration is an investment in long-term operational efficiency, not just a line item. If you're ready to migrate to Shopify and want a partner who handles the entire process — from account setup through your development store build, launch, and ongoing optimization — book a discovery call.
