If you’re still on Magento, whether it’s the end-of-life Magento 1 or the increasingly expensive Magento 2 / Adobe Commerce, you already know the clock is ticking. Hosting costs are climbing. Finding Magento developers is getting harder and more expensive. Every update feels like open-heart surgery on your store. And meanwhile, the brands you compete with have migrated to Shopify Plus and are moving faster than you.
The migration from Magento to Shopify Plus is the most common, and most complex, replatforming project in ecommerce. We’ve done enough of them to know exactly where they go wrong, what needs to happen in what order, and how to protect your revenue through the transition. This is the playbook.
Why Brands Leave Magento
The reasons are consistent across nearly every Magento brand we talk to.
Total cost of ownership. Magento is open-source in theory but expensive in practice. Hosting, security patching, PCI compliance, developer time for every update and custom module maintenance can push the annual cost of running a Magento store above $50K to $150K before you build a single new feature. Shopify Plus eliminates most of that infrastructure overhead. (If you’re weighing the platform fee itself, see whether Shopify Plus is worth the monthly cost.)
Developer scarcity. The Magento developer pool has been shrinking for years. The best Magento developers have migrated to other platforms or moved into higher-paying roles. The ones who remain command premium rates. Finding someone who can work on your specific Magento codebase, with its custom modules and years of technical debt, is increasingly difficult.
Speed to market. On Magento, launching a new product collection, updating your checkout flow or adding a subscription program requires weeks of development. On Shopify Plus, these changes take days. For brands competing in fast-moving categories like fashion, beauty and food, that speed differential is a competitive disadvantage.
Security and compliance burden. Magento stores are frequent targets for attacks: credit card skimmers, brute-force attempts and exploits against unpatched vulnerabilities. The PCI compliance burden falls entirely on the merchant. Shopify Plus handles security, PCI compliance and hosting as part of the platform.
The Migration Workstreams
A Magento-to-Shopify-Plus migration has six parallel workstreams. Treating any of them as secondary is how migrations fail.
1. Data Migration
This is the highest-risk workstream. Magento and Shopify have fundamentally different data models. Products, variants, customers, orders, subscriptions, gift cards, discount rules and metafields each require mapping, transformation and validation.
Key risks:
- Magento’s configurable products don’t map directly to Shopify’s variant system. Products with many attributes may need restructuring.
- Customer passwords cannot be migrated. Every customer will need to reset their password on the new store. Plan communication for this.
- Order history can be migrated for reference, but transactional data (refunds, returns) may require manual handling.
- If you’re running subscriptions on Magento (via Bold, Amasty or custom), the subscription data migration is its own sub-project. Billing dates, frequencies and payment tokens all need to transfer cleanly. See our guide to migrating subscriptions to Shopify.
Best practice: Run at least three test migrations on staging before the live cutover. Validate data counts, spot-check records, and test edge cases (products with 50+ variants, customers with 100+ orders, subscriptions with custom frequencies).
2. URL Redirect Mapping
This is the SEO workstream, and it’s non-negotiable. Magento and Shopify use different URL structures. Every product, collection, category, CMS page and blog post URL needs a 301 redirect from the old path to the new path.
Key risks:
- Magento’s category-based URLs (/women/dresses/summer-dress.html) don’t exist in Shopify’s flatter structure (/products/summer-dress). Every category path needs a redirect.
- Magento generates canonical URLs and parameter-based URLs that also need redirecting.
- Image URLs change during migration. If other sites hotlink your product images, those links break.
Best practice: Export every indexed URL from Magento using Screaming Frog or a similar crawler. Map each to its Shopify equivalent. Load redirects before launch. Monitor organic traffic daily for the first 30 days post-launch. This is the core of ecommerce SEO during a migration.
3. Design and UX
The migration is an opportunity to redesign, not just replicate. Most brands use the replatform as the trigger for a full visual refresh. The design workstream runs in parallel with data migration, not after it.
4. App and Integration Replacement
Every Magento extension needs a Shopify equivalent. Review your full app stack (payment gateways, shipping calculators, tax automation, ERP/OMS integrations, review platforms, loyalty programs, email/SMS tools) and identify the Shopify replacement for each. Some will be native Shopify features. Some will be third-party apps. Some may require custom development.
5. Custom Functionality
Any custom-built Magento functionality (product configurators, custom pricing rules, B2B portals, wholesale pricing, multi-warehouse logic) needs to be replicated or replaced on Shopify Plus. This is where Shopify Scripts, Shopify Functions and checkout extensibility come in.
6. QA and Launch
Test everything. Every product page, every collection, every checkout flow, every integration, every email trigger, every redirect. Test on mobile. Test on slow connections. Test with real customer data. Then test again.
The Timeline
A straightforward Magento-to-Shopify-Plus migration, with fewer than 5,000 SKUs, standard integrations and no complex custom functionality, takes 10 to 14 weeks.
A complex migration, with 10,000+ SKUs, subscription programs, B2B functionality, ERP integration or a headless frontend, takes 16 to 24 weeks.
The brands that stay on schedule are the ones that start data migration and redirect mapping in week one, not week six.
What Most Agencies Get Wrong
They underestimate data complexity. The agency pitches a clean migration timeline, then discovers three weeks in that Magento’s product data is messy, customer records have duplicates, and the subscription data doesn’t map cleanly. The timeline slips.
They treat redirects as a post-launch task. Redirects need to be planned and built during the project, not scrambled together on launch day.
They don’t run test migrations. One test migration isn’t enough. You need multiple rounds to catch edge cases and validate data integrity. The cost of an extra week of testing is trivial compared to the cost of broken data in production.
They don’t plan the customer communication. Your customers will need to reset their passwords. Your subscription customers may need to re-enter payment details. If you don’t communicate this clearly and proactively, your support team will be overwhelmed and your customers will be frustrated.
