A Shopify to Medusa Migration Checklist for Revenue-Safe Launches
What to validate before, during, and after a migration so product data, customers, redirects, checkout, and reporting stay reliable.
By Lyzant
A Shopify to Medusa.js migration moves products, customers, order history, checkout behavior, URLs, and integrations from Shopify into a custom Medusa.js commerce architecture.
The safest Shopify to Medusa.js migrations are sequenced around revenue risk: checkout, payments, pricing, redirects, and customer access come before cosmetic rebuild work.
Pre-Migration Checklist
- Inventory products, variants, collections, customers, orders, discount rules, URLs, and third-party integrations.
- Decide which Shopify behaviors need exact replacement and which should be redesigned in Medusa.js.
- Map payment, shipping, tax, analytics, fulfillment, and email workflows before import work starts.
- Identify high-value URLs and create an SEO redirect map before launch.
Validation And Launch Controls
Run migration dry-runs with validation reports. Counts are not enough; spot-check product relationships, tax behavior, search visibility, order history, discount behavior, and customer account access.
- Validate catalog relationships, product options, images, pricing, and stock states.
- Test checkout with real payment, shipping, tax, and failure scenarios.
- Compare analytics, conversion tracking, and order-state reporting before and after launch.
- Keep a post-launch stabilization window where defects are triaged daily.
SEO Risks To Control
SEO risk usually comes from changed URLs, missing metadata, broken canonicals, poor redirect coverage, and thin replacement pages. A migration plan should preserve important routes, update the sitemap, and monitor Search Console after launch.
