WooCommerce to Shopify Migration: What Actually Breaks

The WooCommerce-to-Shopify migrations we’re getting in 2026 don’t sound like the ones from five years ago. The merchant who wants to leave WordPress because it’s hard to maintain is still out there, but the more common conversation now is “we picked Woo to keep early costs down, we hit a ceiling, and we need to grow past it.”

This guide walks through one of those migrations end to end. It’s a real engagement, anonymized: a home goods brand, DTC, around $720K annual revenue and growing 30% year over year when they came to us. We covered the parts that actually mattered, including the thing nobody plans for that adds a week to every migration.

Why merchants leave WooCommerce in 2026

The reasons have shifted. Five years ago, the dominant story was “WordPress is hard to maintain.” That’s still true, but it’s no longer the main driver. Two newer reasons are pushing migrations.

Hitting the enterprise ceiling. WooCommerce is excellent at zero-to-half-a-million. Past that, the platform starts to fight you. Native subscriptions, Shop Pay-equivalent express checkout, B2B account approval flows, headless storefronts, international subdomains: WooCommerce can do all of these via plugins, but nothing is first-party. Every feature is an integration risk, and the integration risks compound.

Our client hit this exact wall. They wanted Shop Pay (which alone increases mobile checkout completion meaningfully on Shopify), native subscriptions for their consumable replenishment line, and a clean path to a wholesale portal for the B2B accounts they were starting to win. Each was possible on Woo. None were clean.

Hosting under load. Our client had three Black Friday outages in 2024 under traffic spikes their managed WordPress host couldn’t absorb. The host blamed plugins, the plugin vendors blamed the host, the merchant lost the day’s revenue both ways. Shopify’s infrastructure removes this entire category of problem.

The thing nobody plans for

We’ve done enough Woo-to-Shopify migrations to know the data import is rarely where projects stall. Products, customers, orders: there are tools, the data shape is well-understood, and the bulk imports run overnight.

What stalls projects is the custom logic a freelancer wrote two years ago that nobody documented.

Our client’s checkout had three custom fields: a secondary delivery address (separate from billing/shipping for their B2B accounts), a “this is a warranty claim” flag, and an order reference code used by their back-office for routing. A freelancer had built this in 2023 using a WooCommerce checkout plugin that’s no longer maintained. The merchant had forgotten it existed until our discovery call when a team member said “oh, and the wholesale orders go to a separate queue.”

There’s no native Shopify equivalent. On vanilla Shopify, line item properties get you close but don’t trigger different fulfillment routing. The right answer in 2026 is a Shopify Function, which is what we built. It validates the fields at checkout, attaches them as cart attributes, and triggers a tagging rule that routes wholesale orders to a separate Shopify Flow.

This added a week to the project we hadn’t quoted. The lesson, which applies to every migration: the brief always undercounts the custom logic. Budget a week of contingency for “the thing nobody mentioned” and you’ll be right about 80% of the time.

The migration order we actually use

In rough order of risk:

1. Inventory and pricing audit. Before touching anything, export the full WooCommerce product catalog and reconcile it against what the merchant thinks they sell. Discontinued SKUs, draft products, duplicate variants from a deprecated plugin: clean this in Woo before migrating, not after.

2. URL mapping. WooCommerce uses /shop/product-category/product-name/. Shopify uses /products/product-name. Every existing URL needs a 301 redirect. Our client had 4,200. We exported them as a CSV from Woo, transformed in a spreadsheet, and imported using Shopify’s native URL redirects (not .htaccess, which dies with WordPress). Shopify’s documented migration path covers the mechanics.

This is where SEO traffic gets lost. Skip it and you’ll see organic drop within weeks.

3. Product data import. Standard tools (Matrixify, LitExtension, or Shopify’s own importer) handle the bulk. Watch for variant images (Woo and Shopify model them differently), HTML in product descriptions (Woo’s TinyMCE output often has inline styles that look wrong in Shopify’s theme), and any custom taxonomies that don’t map to collections.

4. Customer accounts. Customers can be imported but passwords cannot. Shopify will send an account activation email on first login. Plan a communication: an email explaining the migration and what to expect, sent the day of cutover.

5. Order history. Optional but worth doing. If a customer needs to dispute a charge or return a 6-month-old order, you want the history searchable. Order import is its own multi-CSV exercise.

6. Subscriptions. If you’re on WooCommerce Subscriptions, this is its own project. You can’t directly migrate active subscriptions to Shopify Subscriptions. You either rebuild them via Shopify’s native subscriptions or via a third-party (Recharge, Bold). Either way, customers re-authorize. Plan this carefully.

7. Custom checkout logic. See above. This is where Shopify Functions earn their keep.

8. Cutover. Final inventory sync, DNS switch, redirects activated. Pick a low-traffic window. Have rollback ready (don’t delete the Woo site for at least 30 days).

Protecting SEO

The single most important thing: don’t change URLs that you don’t have to. Where Woo’s structure requires a change, redirect. The 4,200 redirects we set up for our home goods client mapped every legacy product URL, every category URL, every paginated archive page, and the blog (which used /news/ on Woo and /blogs/news/ on Shopify).

Post-launch, monitor Search Console daily for the first 30 days. Watch for:

• Coverage errors (404s on URLs that should be redirecting)
• Sudden drops in impression count for any specific page
• Sitemap submission errors

Our client launched on a Tuesday morning and went live with the new sitemap submitted to Search Console the same day. Thirty days post-launch: zero organic traffic loss, +18% mobile conversion rate in the first month (almost entirely from the speed improvement, since Shopify’s hosting outperformed their old WP host significantly).

What WooCommerce still does better

This isn’t a “Shopify is always better” post. WooCommerce wins on:

• Per-transaction cost at scale below ~$2M/year if you’re staying on Shopify Standard
• Total customization freedom (it’s PHP source you own)
• Content-first sites where the store is secondary to the editorial (WordPress is genuinely better at this)
• Stores that need WordPress-specific integrations (a learning management plugin, a membership site, a directory)

If any of those describe your store and you’re stable on Woo, “everyone is migrating” isn’t a good reason to migrate. The reasons should be specific: hitting a ceiling, hosting can’t handle your traffic, or the maintenance burden is consuming a developer.

When to start

If you’re migrating to capture a peak (Black Friday, a product launch, a wholesale rollout), start at least eight weeks before the date. Six is possible. Four is tight and skips contingency. Two is “you will launch broken or miss the date.”

If you’re coming from BigCommerce instead, the same playbook with platform-specific gotchas is in our BigCommerce to Shopify migration guide. Wondering what a new build will cost post-migration? See how much a custom Shopify store costs in 2026.

If you’d like a migration scoped specifically, book a discovery call or read about our Shopify design and development services. We’ve done enough of these to spot the freelancer-built custom logic in the first 20 minutes.
