Migrating from Magento to Shopify Plus is one of the most complex platform transitions in ecommerce. Done right, it dramatically reduces infrastructure complexity, server costs, and development overhead. Done wrong, you lose SEO rankings, corrupt customer data, and break critical business workflows.
This complete checklist covers every phase from pre-migration audit to post-launch monitoring, with the specific technical details that matter most.
Pre-Migration: Audit & Planning
Magento Audit
- Export full product catalog (SKU count, attributes, variants, images)
- Export customer database (emails, addresses, order history)
- Document all custom Magento extensions and their functions
- List all third-party integrations (ERP, 3PL, CRM, email platform)
- Crawl all URLs with Screaming Frog (export full URL list)
- Document Magento URL structure (/category/subcategory/product.html patterns)
- Record top 100 pages by organic traffic in Google Search Console
- Document all custom pricing rules, discount codes, and B2B tiers
- Identify all custom checkout steps or payment integrations
- Map all CMS pages, blog posts, and static content
Shopify Plus Setup Planning
- Determine store structure (single store vs. multi-store with expansion stores)
- Plan Shopify Plus features to use: Flow, Launchpad, Scripts, Functions
- Evaluate Shopify Plus apps for B2B pricing (if applicable)
- Plan checkout extensibility replacements for custom Magento checkout steps
- Select theme approach: Shopify 2.0 theme (OS 2.0) or custom theme build
- Plan Shopify Markets setup for international stores
Phase 1: Data Migration
Products and Catalog
- Export Magento products to CSV with all attributes
- Map Magento custom attributes to Shopify metafields or tags
- Convert product images to WebP, validate dimensions (main: 2048px+)
- Import products via Shopify’s bulk import CSV or API
- Verify variant structures (Shopify: max 3 option types, 100 variants per product)
- Map Magento categories to Shopify collections (create collection rules where possible)
- Verify product URLs match planned redirect map
Customers
- Export customer records with addresses, tags, order history
- Import via Shopify Admin API (not CSV — API preserves more data)
- Note: Magento password hashes cannot transfer. Customers must reset passwords.
- Prepare “password reset” email campaign to send at launch
- Migrate customer segments/groups to Shopify customer tags
Orders and History
- Decide whether to migrate historical orders (important for customer service, loyalty)
- Use a migration tool (LitExtension, Cart2Cart) or custom API migration for order history
- Verify customer lifetime value data transfers to your CRM/email platform
Phase 2: SEO Preservation
URL Redirect Mapping
- Create redirect map: every Magento URL → Shopify equivalent
- Prioritize pages with significant organic traffic first
- Map /catalog/category/view/id/ URLs to Shopify collection URLs
- Map /catalog/product/view/id/ URLs to Shopify product URLs
- Map CMS page URLs (/about-us.html → /pages/about-us)
- Import redirects in bulk via Shopify Admin (CSV import)
- Verify redirect chains don’t exceed 2 hops
- Test all top 100 traffic URLs post-redirect implementation
Meta Data Migration
- Transfer meta titles and descriptions for all products and collection pages
- Preserve structured data (Product schema, BreadcrumbList)
- Update internal links to use new Shopify URLs
- Submit new XML sitemap to Google Search Console post-launch
Phase 3: Custom Functionality Replication
Mapping Magento Features to Shopify Plus
Every custom Magento feature needs a Shopify equivalent. Common mappings:
- Magento layered navigation → Shopify collection filters (Shopify 2.0 theme with filter UI)
- Magento customer groups → Shopify customer tags + app (e.g., Wholesale Club for B2B pricing)
- Magento promotions engine → Shopify Discounts + Shopify Functions (custom discount logic)
- Magento custom checkout steps → Shopify Checkout Extensibility (Plus only)
- Magento ERP integration → Rebuild via Shopify Admin API + webhooks
- Magento multi-warehouse → Shopify Locations (up to 1,000 on Plus)
Phase 4: Theme Development
- Build or configure Shopify theme to match approved designs
- Implement Shopify OS 2.0 sections everywhere for merchant flexibility
- Build custom product page sections for complex product types
- Optimize theme for Core Web Vitals (target LCP < 2.5s)
- Test on iOS Safari, Android Chrome, and desktop browsers
- Validate checkout flow end-to-end (all payment methods, all shipping zones)
Phase 5: Integration Reconnection
- Reconnect email platform (Klaviyo, Mailchimp) with new Shopify store
- Verify all automated flows (welcome, abandoned cart, post-purchase) trigger correctly
- Reconnect ERP/3PL via Shopify API webhooks — test order creation, fulfilment, and cancellation flows
- Reconnect payment gateways — test all payment methods in staging
- Set up Shopify Payments or preferred gateway with correct tax settings
Phase 6: Pre-Launch Testing
Pre-Launch Checklist
- Place test orders through all payment methods
- Test all discount codes and automatic discounts
- Verify all email notifications send correctly
- Test complete checkout flow on mobile (iOS and Android)
- Verify all URL redirects work (spot-check 50+ URLs)
- Confirm all product images load correctly
- Test site search (verify product titles return correct results)
- Check all CMS pages and blog posts display correctly
- Run Lighthouse on homepage, collection page, product page — score ≥ 70 mobile
- Verify Google Analytics / GA4 events firing correctly
- Verify Meta Pixel and Google Ads conversion tags
- Test 404 handling (non-redirected URLs should show custom 404 with search)
Post-Launch Monitoring
- Monitor Google Search Console for crawl errors and indexing issues daily for 2 weeks
- Track organic traffic vs. pre-migration baseline (expect 2–4 week fluctuation)
- Monitor conversion rate vs. Magento baseline
- Set up uptime monitoring (Pingdom, Better Uptime)
- Monitor customer support ticket volume — password reset requests are expected
Frequently Asked Questions
Most teams move to cut the operational weight of Magento — server costs, security patching, extension conflicts, and the developer time needed just to keep it running. Shopify Plus is fully hosted, so infrastructure, PCI compliance, checkout, and scaling for traffic spikes are handled for you, freeing budget for growth instead of maintenance. The trade-off is less low-level control, which is why mapping your custom Magento features to Shopify equivalents is the critical planning step.
A typical mid-size migration (10,000–100,000 SKUs, 3–5 custom features) takes 8–16 weeks end-to-end. Large enterprise migrations with complex B2B pricing, ERP integrations, and multi-store setups can take 6–12 months.
Migration costs range from $15,000–$25,000 for straightforward stores to $50,000–$150,000+ for complex enterprise migrations with significant custom functionality, ERP integrations, and B2B pricing systems.
Migratable data includes: products, variants, images, categories/collections, customers, order history, CMS pages, blog posts, and reviews. Data that requires custom mapping: custom product attributes, B2B pricing tiers, complex discount rules, and loyalty points.
It depends on how much you rely on order history. Migrating it matters for customer service, loyalty and lifetime-value calculations, and returns on past purchases — but it adds time and usually needs a migration tool (LitExtension, Cart2Cart) or a custom API migration. If history isn’t operationally critical, many stores archive the old Magento data and start fresh, keeping a read-only export for reference. Decide before Phase 1, since it affects scope and cost.
You can’t transfer the passwords — Magento password hashes are incompatible with Shopify, so every customer must reset. The clean approach: import customer records (emails, addresses, tags, order history) via the Shopify Admin API, then send a branded ‘set your new password’ email at launch. Warn your support team to expect a spike in password-reset questions in the first days, and make the reset flow obvious on the storefront.
Not if you implement proper URL redirects. Map all Magento URLs to Shopify equivalents and implement 301 redirects before launch. Also preserve: meta titles/descriptions, canonical tags, structured data, and internal link structure.
Usually yes, but with different building blocks. Magento layered navigation maps to Shopify collection filters; customer groups to customer tags plus a B2B/wholesale app; the promotions engine to Shopify Discounts and Functions; custom checkout steps to Checkout Extensibility (Plus only); ERP and multi-warehouse to the Admin API plus Shopify Locations. The work is rebuilding each custom feature as its Shopify equivalent — audit them all up front so nothing critical is discovered missing after launch.
