WooCommerce works well until it doesn’t. It’s usually not one dramatic failure — it’s a slow accumulation of plugin conflicts, hosting headaches, and a site that gets harder to maintain every time traffic spikes. At that point, Shopify Plus starts looking less like an upgrade and more like a necessity.
Migrations are one of the most requested projects at Knit Agency, and they’re also where the most expensive mistakes happen — not during planning, but in the details nobody thought to check. Here’s what actually breaks, and how to plan around it.
Why Brands Make This Move
- WordPress core, theme, and plugin updates conflict often enough that every update becomes a small risk
- Hosting has to scale manually — a traffic spike from a good marketing push can bring the site down instead of converting
- Multiple disconnected plugins for cart, checkout, subscriptions, and reviews create a fragile stack instead of a stable platform
- Shopify Plus centralizes hosting, checkout, and scaling into a single managed environment purpose-built for high-growth ecommerce
What Typically Breaks During Migration
| Area | What Goes Wrong | How to Avoid It |
|---|---|---|
| URL structure | WooCommerce and Shopify use different URL patterns by default, breaking inbound links and rankings | Map every URL and set up 301 redirects before launch, not after |
| SEO metadata | Meta titles, descriptions, and alt text often don’t migrate automatically | Export and re-map metadata field by field, don’t rely on the import tool alone |
| Product variants | Complex variant/attribute structures in WooCommerce don’t map 1:1 to Shopify’s variant model | Audit variant logic early; Shopify has hard limits (e.g., 3 option types per product) |
| Custom fields & metafields | Custom product data (size charts, care instructions, technical specs) often lives in custom fields with no direct Shopify equivalent | Plan a metafield structure in Shopify before importing, not after |
| Reviews & UGC | Product reviews rarely migrate cleanly and can be lost entirely if not handled deliberately | Export reviews manually and re-import via a review app (e.g., Stamped) tied to matching product IDs |
| Subscriptions | Recurring billing logic doesn’t transfer automatically between platforms | Plan subscription migration with the app provider (e.g., Recharge) well before cutover |
| Customer accounts & order history | Passwords can’t be migrated for security reasons; order history needs manual mapping | Communicate a password reset flow to customers in advance |
| Custom plugin functionality | Anything built on a specific WooCommerce plugin (custom pricing rules, complex shipping logic) needs to be rebuilt, not imported | Inventory every plugin and its function before scoping the project |
A Realistic Migration Timeline
- Discovery & audit (1–2 weeks) — full inventory of plugins, custom functionality, content, and SEO assets
- Platform & app mapping (1–2 weeks) — matching every WooCommerce feature to its Shopify Plus equivalent (native or app-based)
- Build & data migration (4–8 weeks) — theme development, metafield structure, product and customer data migration
- QA across devices and browsers (1–2 weeks) — checkout flows, forms, redirects, and mobile experience specifically
- Staged launch with monitoring (1 week) — redirect verification, search console monitoring, and a rollback plan in place
Before You Migrate: A Quick Checklist
- [ ] Full export of product, customer, and order data completed and backed up
- [ ] Every current URL mapped to its new Shopify equivalent with 301 redirects planned
- [ ] List of every active plugin and what it does, with a Shopify equivalent identified for each
- [ ] SEO baseline recorded (rankings, traffic, indexed pages) to measure against post-launch
- [ ] Customer communication plan ready for password resets and any account changes
- [ ] Staging environment tested end-to-end before DNS cutover
Our Take
The migrations that go smoothly are the ones where the audit takes longer than expected — because that’s where the expensive surprises get caught before launch, not after. Rushing straight into theme development without mapping every plugin, metafield, and URL is the single most common cause of post-launch SEO and functionality issues we see.
