7 Mistakes That Ruin a WooCommerce to Shopify Migration

Most WooCommerce to Shopify migrations that go wrong don't fail because the platforms are incompatible. They fail because someone skipped a step, moved too fast, or assumed the tool would handle it automatically. The result: broken SEO, missing customer data, incorrect redirects, and a store that's technically live but commercially damaged.

These are the 7 mistakes we see most often — and what to do instead.

1. Not Auditing Your WooCommerce Data Before You Export

The first mistake is also the most avoidable. Before you touch an export tool, you need to know exactly what data you have in WooCommerce — and more importantly, what shape it's in.

Most WooCommerce stores have accumulated years of product variation mismatches, duplicate SKUs, orphaned images, customer records with blank email fields, and orders in custom statuses that don't map anywhere. If you migrate dirty data, you import dirty data. Shopify won't clean it for you.

• Run a product export from WooCommerce and open it in Excel. Check for blank titles, missing SKUs, broken image URLs.
• Export customer data and check for duplicates and empty required fields.
• Review your order history — decide upfront how far back you want to go (importing 7 years of orders slows things down and adds noise).

A one-hour audit before you start saves 20 hours of cleanup after the migration.

2. Ignoring URL Structure Changes

WooCommerce gives you full control over your URL structure. Shopify doesn't. Product URLs on Shopify follow a fixed pattern: /products/product-handle. Blog posts go to /blogs/news/post-handle. Collection pages live at /collections/collection-handle.

If your WooCommerce store had URLs like /shop/category/product-name or /product/item-slug, every single one of those URLs changes. Without 301 redirects, every backlink you've earned, every page Google has indexed, and every link a customer bookmarked stops working.

The fix is straightforward but non-negotiable:

1. Crawl your current WooCommerce site with Screaming Frog before migration — export every indexed URL.
2. Map every old URL to its new Shopify equivalent.
3. Import all redirects using Shopify's URL redirects feature (CSV import is available in Settings → Navigation).
4. After go-live, run the crawl again and check for 404 errors.

Skipping this step is the single fastest way to lose six months of SEO in one afternoon.

3. Picking a Shopify Theme Without Mapping Your Current Store

Shopify's theme marketplace is full of great options. But picking a theme without mapping your current site's structure — page templates, product layouts, collection filters, navigation tiers — leads to a store that technically works but converts worse than what you had before.

Don't just ask "does this theme look good?" Ask: does it support the product features I rely on (variants, bundles, subscriptions)? Does it have the navigation depth I need? Can the checkout flow be customised the way my customers expect?

The smarter move is to document your current WooCommerce site's top-performing pages and design backwards from those — not forwards from a template. A theme that looks great in a demo but doesn't match your product catalogue structure will cost you conversion rate from day one.

4. Trusting an Automated Migration Tool Without Checking the Output

Tools like LitExtension, Cart2Cart, and Matrixify do a lot of heavy lifting. They're genuinely useful. But treating them as set-and-forget is a mistake.

What automated tools commonly miss or mishandle:

• Product variants — WooCommerce's variation structure doesn't always map cleanly to Shopify's option/value system, especially if you used conditional variations or custom fields.
• Custom meta fields — any custom product data stored in WooCommerce meta won't transfer unless explicitly mapped.
• Order statuses — WooCommerce supports custom order statuses from plugins; Shopify has a fixed set. Unmapped statuses either error or get dumped as "fulfilled."
• Image alt text — often stripped during transfer, hurting both accessibility and SEO.

After any automated migration, manually QA a sample of 20–50 products, 10 customer records, and 5 historical orders. It's tedious. Skip it and you'll regret it.

5. Forgetting to Test Payment Gateways and Tax Rates Before Go-Live

Shopify's payment setup is different from WooCommerce's. Shopify Payments, Stripe, PayPal, and third-party gateways all have different configuration steps, and tax rules work differently depending on whether you're using Shopify Tax or a third-party app.

The mistake: going live without placing test orders through every payment method you intend to accept. One missed tax rate configuration on a product category can mean you're either overcharging customers or remitting less than you owe to the tax authority.

Before launch:

1. Enable Shopify's test mode and run a successful order through every payment gateway.
2. Check tax calculations against what you were collecting on WooCommerce — by product type, by customer region.
3. Confirm that order confirmation emails are triggering correctly with the right details.

6. Not Planning for Customer Password Migration

WooCommerce passwords are hashed using WordPress's encryption. Shopify uses a completely different system. You cannot migrate hashed passwords — it's technically impossible without storing plain-text passwords, which no responsible platform does.

What this means in practice: every customer will need to reset their password after migration. If you don't tell them proactively, they'll hit your login page, fail to sign in, and assume the store is broken. You'll see support tickets spike and trust erode in the first week.

The fix is simple. Send a proactive email to your customer list on migration day explaining the change and linking directly to the password reset page. Most good migration partners handle this as standard — it's a red flag if yours doesn't mention it.

7. Going Live Without a Rollback Plan

The last mistake isn't about data or configuration — it's about confidence. Specifically, the overconfidence that says "it'll be fine" without asking "what if it's not?"

Your WooCommerce store should stay live and untouched until Shopify is fully QA'd, all redirects are in place, all payment methods are tested, and you have a clear window for DNS propagation. DNS changes can take up to 48 hours to propagate globally. If something goes wrong at hour 3 of that window, you need to be able to roll back quickly.

• Keep your WooCommerce hosting active for at least 30 days post-migration.
• Don't delete product listings, customer data, or order history from WooCommerce until everything on Shopify is verified.
• Document your migration cutover plan in writing — even a one-page checklist is enough to stop the chaos when things don't go perfectly.
