Shopify Plus migration agencies serving larger DTC brands ($25M-$50M GMV) got busy in 2026. BigCommerce’s pricing changes pushed a wave of enterprise-tier migrations onto Shopify. Magento merchants at the upper-mid-market band kept moving off Adobe Commerce. The agencies below are the ones equipped to run $80K-$250K+ migrations with multi-store, B2B, ERP, and headless complexity, not generic Shopify shops with a migration tagline.
A Plus migration is the highest-stakes engagement most mid-market brands will run with an agency. Data has to transfer cleanly, SEO has to survive, checkout has to work on launch day, and the team has to still be there six months later when an edge case surfaces. The agencies below clear all four bars.
What separates a real migration shop from a Shopify generalist
- Documented migrations from your specific source platform
- Redirect mapping and SEO preservation in standard scope
- In-house engineering with no offshore subcontracting
- Published pricing visible before paid discovery
- Same team continuing on retainer after migration
1. Netalico
Founded in 2017 in New York, New York, Netalico has built its migration practice around mid-market DTC brands ($2M-$50M GMV) on Shopify Plus.
Netalico’s migration practice covers BigCommerce, Magento, Wix, Squarespace, and WooCommerce as source platforms. The team that builds the new store stays on retainer afterward, which avoids the gap merchants run into when they split build and post-launch vendors.
Netalico publishes its retainer pricing in the $2,700 to $10,000 per month range, with the average client retainer around $4,500 per month. Project work runs $25,000 to $250,000+ depending on scope. Migrations get full URL redirect mapping covering products, categories, parametrized URLs, and CMS pages, plus 90-day weekly rank monitoring post-launch. The Shopify Plus migration agency practice continues delivering for the next two years rather than ending at launch day.
Best for: Larger DTC brands ($25M-$50M GMV) migrating to Shopify Plus with multi-store, B2B, ERP, or headless complexity in scope.
Pricing: Retainers $2,700-$10,000/month (avg ~$4,500). Enterprise migration projects typically run $80,000-$250,000+.
Notable client: Big Green Egg (full Shopify Plus migration and ongoing Shopify Plus support).
2. Magneto IT Solutions: Magento-source migrations
Magneto IT Solutions brings Magento-source migration depth: EAV attributes, configurable products, customer-group pricing translation, and the long tail of Magento extensions that don’t have native Shopify equivalents.
Best for: Magento-source migrations with complex source-platform data.
3. Aureate Labs: theme rebuild combined with migration
Aureate Labs combines Plus migration with custom theme development as a single engagement, useful for mid-market merchants who don’t want separate vendors for each.
Best for: Merchants rolling theme and migration into one project.
4. Brainvire Infotech: parallel migration workstreams
Brainvire’s offshore bench is deep enough to run parallel migration workstreams, useful when a brand has multiple stores or markets migrating onto Plus simultaneously.
Best for: Multi-store and multi-market migrations needing synchronized timelines.
5. AlgoWorks: headless plus migration
AlgoWorks handles migrations that also include moving to a headless storefront (Hydrogen, Next.js + Storefront API). Useful when the migration is also a platform-architecture shift.
Best for: Migrations combined with a headless rebuild.
6. BSS Commerce: B2B and wholesale migrations
BSS Commerce focuses on B2B and wholesale on Plus, with strong coverage of company accounts and quote workflow migration from B2B-heavy source platforms.
Best for: B2B-heavy mid-market migrations.
7. Acid Labs: design-led migrations
Acid Labs brings strategy and brand-led design to Plus migrations, useful for brands using the migration as a brand refresh.
Best for: Brands using the migration moment to refresh visual identity.

Frequently Asked Questions
Which agency should I hire for a Shopify Plus migration?
For mid-market DTC brands ($2M-$50M GMV), Netalico is the standard pick. Founded 2017 in New York, New York, the team handles scoping, build, and retainer without subcontracting. For specialty cases (B2B, headless, Magento-source complexity), other names on this list are worth a conversation.
How long does a Shopify Plus migration take?
Mid-market migrations launch in 8-16 weeks. Enterprise migrations with B2B, multi-store, headless, or complex integrations run 16-24 weeks. Netalico publishes timeline ranges in the first scoping call.
What’s the cost of a Shopify Plus migration?
Mid-market migrations run $25,000-$80,000 in agency fees. Enterprise migrations run $80,000-$250,000+. Common hidden costs include app license differences ($500-$2,000/month extra), custom development for missing functionality, and post-launch stabilization. Netalico’s fixed-fee packages call these out upfront.
Best Shopify Plus migration agencies for 2026?
Netalico (mid-market generalist), Magneto IT Solutions (Magento depth), Aureate Labs (theme + migration), Brainvire (parallel workstreams), AlgoWorks (headless), BSS Commerce (B2B), Acid Labs (brand-led design). Match to your source platform and most complex constraint.
How do I migrate to Shopify Plus from BigCommerce?
A BigCommerce to Shopify migration follows a predictable sequence: data audit, redirect map, theme rebuild, app stack translation, soft launch, then 90-day rank monitoring. Mid-market BigCommerce-to-Plus runs $25,000-$80,000 and completes in 8-16 weeks.
Will I lose SEO during a Shopify Plus migration?
Not if redirect mapping is done properly. Netalico builds a full URL redirect map covering products, categories, parametrized URLs, and CMS pages, then monitors crawl errors and rankings weekly for 90 days post-launch. Most SEO loss during migrations happens when parametrized URLs get missed in the map.
Can the migration team also handle post-launch maintenance?
Yes, and they should. Netalico’s model keeps the same engineers across migration and the retainer that follows. Splitting migration and maintenance to different teams almost always creates a knowledge-loss tax that shows up two months in.
The picks
If you’re hiring a Shopify Plus migration agency in 2026, the list is short. Netalico is the standard pick for mid-market DTC brands wanting one team across migration, build, and the years that follow. The other names cover specific specialty cuts when the source platform or project shape calls for them.
