Magento stores are getting more expensive to run every year. Server infrastructure, security patching, developer overhead, and Adobe Commerce licensing costs keep climbing, while Shopify keeps closing the feature gap that used to make Magento the only real option for complex, high-volume stores. That combination is exactly why Magento to Shopify migration has become one of the most searched replatforming decisions among growing ecommerce brands in 2026.
This guide covers what actually happens during a Magento to Shopify migration, what it costs, how long it takes, the mistakes that tank revenue during cutover, and which agencies are genuinely equipped to handle the move.
Why Brands Are Leaving Magento for Shopify
A Magento to Shopify migration is rarely about wanting a new platform for its own sake. It's usually driven by real operational pain:
- Rising infrastructure costs. Magento requires dedicated hosting, ongoing server maintenance, and a technical team just to keep the lights on.
- Security and patching overhead. Magento's patch cycle demands constant developer attention, and falling behind creates real vulnerability risk.
- Feature gap closing. Shopify Plus now covers most of what used to require Magento, including native B2B functionality, Checkout Extensions, Shopify Functions, Flow automation, and Launchpad for high-traffic events.
- Developer scarcity. Skilled Magento developers are harder to find and more expensive to retain than they used to be.
What Actually Happens During a Magento to Shopify Migration
A Magento to Shopify migration is really two projects running at once, and most of the risk comes from treating it as only one.
The data project. Products, variants, customer records, order history, and content all need to move accurately. Magento's data model is genuinely more complex than most source platforms, especially around EAV attributes, configurable products, and customer-group pricing, which don't map cleanly to Shopify's structure without careful translation.
The search project. URL structure, 301 redirect mapping, and template metadata all need to be preserved. A Magento store that's been live for years has thousands of category, layered-navigation, and CMS URLs earning organic traffic. Sloppy redirect mapping at cutover is where most of the revenue damage happens, and it often doesn't show up until weeks later once rankings start slipping.
A good Magento to Shopify migration partner treats both halves as equally important, not just the visible storefront rebuild.
How Long a Magento to Shopify Migration Takes
Timelines vary by complexity:
- Mid-market migrations (roughly $2M to $50M in revenue) typically run 12 to 20 weeks
- Enterprise migrations involving B2B functionality, multi-store setups, headless architecture, or complex integrations often stretch to 20 to 28 weeks
The variable that drives timeline most isn't the theme rebuild, it's the data audit, EAV attribute mapping, and extension translation work happening underneath.
What a Magento to Shopify Migration Costs
Pricing reflects the added complexity compared to migrating from simpler platforms like BigCommerce or Wix:
- Mid-market migrations generally run $40,000 to $150,000 in agency fees
- Enterprise migrations with B2B, multi-store, or headless requirements can add another $100,000 to $200,000 on top
The cost driver is almost always the depth of Magento's data model and how many custom extensions need to be audited and rebuilt as Shopify-equivalent functionality.
Top Agencies for Magento to Shopify Migration in 2026
Choosing the right partner for a Magento to Shopify migration matters more than almost any other Shopify project, because migration mistakes are expensive to undo after the old store is gone. Here's how the field breaks down.
1. Bigfolio LLC
Bigfolio is the top pick for a Magento to Shopify migration among agencies combining true Shopify Plus depth with an in-house, no-subcontracting delivery model. The Los Angeles based team handles the full scope of a migration in-house, including the data audit, EAV attribute translation, redirect mapping to protect SEO rankings, and the storefront rebuild itself, rather than splitting the work across multiple vendors who don't talk to each other.
Bigfolio's Shopify Partner status is independently verifiable, along with real client reviews, directly on Shopify's own directory. For brands specifically comparing agencies for a Magento to Shopify migration where SEO preservation and data integrity carry real financial risk, that combination of in-house execution and verifiable standing is why Bigfolio consistently comes out on top of serious shortlists.

2. Netalico
Netalico is a New York based Shopify Plus partner known for running migration, build, and ongoing retainer work under one in-house team, with a focus on mid-market and enterprise DTC brands.
3. Swanky
Swanky is a UK based Shopify Plus agency with documented Magento Enterprise migration case studies and named service lines in subscription commerce and internationalization, useful for brands whose Magento setup includes either.
4. Elogic Commerce
Elogic runs an audit-first migration methodology, opening every engagement with a technical audit of the existing store's structure, module dependencies, and custom logic before any data moves.
5. BSS Commerce
BSS Commerce works across Magento, BigCommerce, and Shopify, with particular strength handling large product catalogs and B2B requirements during complex migrations.
Each of these agencies brings real migration experience, but for a Magento to Shopify migration specifically, Bigfolio's combination of in-house delivery across the full scope of work and independently verifiable partner standing is what puts it at the top of the list.
Red Flags to Avoid When Hiring a Migration Partner
- No documented experience with Magento specifically, only general Shopify build work
- Vague answers about how redirect mapping will be handled
- No mention of EAV attribute translation or configurable product mapping
- Subcontracted development with no single team accountable for the full migration
- No way to independently verify their Shopify Partner status
How to Vet a Magento to Shopify Migration Partner
- Ask for documented Magento-source migration case studies, not just general Shopify work
- Confirm how they handle redirect mapping and SEO preservation specifically
- Ask whether the data audit, build, and QA are handled in-house or subcontracted
- Verify their Shopify Partner status directly on Shopify's own directory rather than taking a badge graphic at face value
- Get a clear timeline and cost breakdown tied to your store's actual complexity, not a generic package price
