This is an illustrative composite scenario. It does not describe any single real organization; it generalizes patterns we see repeatedly across ecommerce replatforming projects. Figures are typical ranges, not one company’s exact numbers.
Context
Picture a growing merchant running WordPress with WooCommerce — a content-rich site with a blog, landing pages, and a catalog of a few thousand products. The store worked, but keeping WooCommerce, its plugins, hosting, and security patched had become a part-time job nobody wanted. Leadership wanted managed commerce: a reliable checkout, less maintenance, and room to scale during peak sales. Shopify was the target.
Moving from an open, do-anything WordPress stack to Shopify’s opinionated platform trades flexibility for reliability — and the friction shows up in the places WordPress let you do whatever you wanted. The projects that struggle are the ones that treat it as a straight content copy rather than a re-platform onto a system with firm rules.
What broke
Shopify’s forced URL structure
This is the big one. Shopify mandates URL prefixes — products live under /products/, categories under /collections/, static pages under /pages/, and blog posts under /blogs/…. WordPress’s clean, custom permalinks almost never match, so every URL changes. Without a complete 301 map covering products, categories, pages, and posts, the store would have lost hard-won product rankings and paid-traffic landing pages overnight.
Catalog and customer data
Products, variants, images, and inventory had to be exported from WooCommerce and imported into Shopify via CSV and a migration app — a mapping exercise where variant structures and custom product fields rarely line up one-to-one. Customer accounts, order history, and product reviews needed their own migration paths, each with caveats (passwords never transfer; reviews depend on the app on each side).
Theme and content rebuild
WordPress themes and page-builder layouts do not run on Shopify, which uses its own Liquid templating. The storefront was rebuilt as a Shopify theme, and content pages were re-created within Shopify’s more limited page and blog model.
Plugins become apps — with monthly costs
WooCommerce plugins map to Shopify apps, but not one-to-one: some features have no equivalent, and many apps carry recurring monthly fees that change the total cost of ownership. Each critical plugin needed an app equivalent identified and priced before commitment, not after.
What worked
The migration succeeded because the team respected Shopify’s rules instead of fighting them. They exported and cleaned the WooCommerce catalog before import, so they were not migrating junk data. They built the redirect map around Shopify’s forced prefixes early and loaded it into Shopify’s URL-redirect tool at launch. They rebuilt the theme in Liquid rather than trying to reproduce the WordPress design exactly, and they selected and priced the replacement apps up front so there were no surprises in the monthly bill.
Lessons
- Plan for total URL change. Shopify’s forced prefixes mean every product, collection, page, and post URL moves — the 301 map is the make-or-break SEO task.
- Catalog migration is a mapping job. Export, clean, and map WooCommerce products and variants; do not assume a clean one-to-one import.
- Migrate customers and orders deliberately. Each has its own path and caveats; passwords never transfer and reviews depend on the apps involved.
- Rebuild the theme in Liquid. WordPress themes and builders do not port; treat the storefront as a rebuild.
- Price the apps before you commit. Plugin-to-app is not one-to-one, and recurring app fees reshape total cost of ownership.
Before you make this move
- Crawl the current store and build a full 301 map to Shopify’s
/products/,/collections/,/pages/, and/blogs/paths. - Export and clean the WooCommerce catalog, and map variants and custom fields to Shopify’s model.
- Decide how customer accounts, orders, and reviews will migrate — and accept what cannot.
- Identify and price the Shopify apps that replace your critical plugins.
- Rebuild the theme in Liquid and carry SEO titles and descriptions across explicitly.
A pre-migration scan makes the redirect scale and content split concrete before you start. Replatform Radar inventories your catalog, URLs, and SEO signals so a move to Shopify preserves the rankings and revenue you already have.
