# Migrating an Auto Parts Store to Shopify Without Losing Fitment Data

> The replatforming playbook for parts stores: where fitment data hides, extracting it to ACES-shaped neutral ground, and verifying before cutover.

## Frequently asked questions

### Can fitment data be migrated from Magento or WooCommerce to Shopify?

Yes, but not by standard migration tools, which move products, customers, and orders and ignore extension-level fitment structures. The working approach extracts application data to a neutral, part-number-keyed format, rebuilds it on Shopify against the new catalog, and verifies application counts before cutover.

### What happens to vehicle landing page SEO in a migration?

It survives only if someone maps it. Vehicle-filtered URLs are platform-generated, so old and new sites produce different patterns, and unredirected patterns quietly drop years of rankings. Crawl the indexed URLs before cutover and redirect at the pattern level, with the highest-traffic pages handled explicitly.

### Should fitment data be cleaned during migration or copied as-is?

Cleaned. The extraction step is the cheapest moment the business will ever have to remove dead vehicles, duplicate applications, and superseded numbers, because the data sits in an auditable, spreadsheet-shaped format between platforms rather than inside a live storefront.

### How do you know the fitment migration worked before going live?

Reconcile application counts per SKU against the extraction, test the top vehicles by historic sales, confirm OEM and competitor numbers resolve in search, and check known-tricky parts by hand. After launch, watch zero-results searches, since a spike there is fitment failure showing up in buyer behavior.
