A Shopify Plus migration is not a theme copy. It is a cross-border business cutover involving URLs, product and customer data, market prices, payments, duties, delivery, ERP or CRM, app replacement, and rollback. Define scope and acceptance before moving data so SEO, orders, and operations have an observable safety plan.
Build data and URL inventories
Create a table for old URL, new URL, status, canonical, title, content, media, links, and redirect. Also inventory products, variants, customers, orders, discounts, stock, apps, and permissions. Do not copy every duplicate or obsolete page; decide through intent and business value while preserving URLs that need to retain demand.
Replay transactions by market
Test product, price, currency, duties, payment, delivery, address, stock, refunds, and support in a representative market. Add special paths for B2B, subscriptions, high-consideration products, and multiple warehouses. Include declines, duplicate submissions, stockouts, refunds, and rollback instead of testing successful orders only.
Observe launch and SEO
Freeze changes before launch and assign rollback owners. After launch check redirects, errors, canonical, sitemap, robots, indexing, analytics, links, orders, payments, stock, and support exceptions. A successful publish is not the same as a completed migration.
FAQ
What should a Shopify Plus migration check first?
URLs, data ownership, payment eligibility, market rules, app replacement, and rollback.
Does migration preserve SEO automatically?
No. Validate URL mapping, redirects, canonical, content, links, and indexing per URL.
Should every old page be migrated?
No. Use intent, business value, links, and historical performance to merge, rewrite, retain, or retire.
How much pre-launch testing is needed?
At least one representative market’s full order loop, plus payment failure, stockout, refund, and support hand-off.
How should a migration case prove results?
State scope, period, problem, acceptance definition, and permission; publish method and risk when private data is unavailable.
