Replatforming looks like a technology swap. It is really a content, SEO, payments, and operations project that happens to include a new storefront.
Teams that treat URL structure, redirects, and catalog quality as afterthoughts pay for months in lost rankings and support tickets.
Non-negotiables before cutover
- Full URL map with 301 redirects for every indexed product and category
- Catalog parity checks: SKUs, variants, media, and inventory rules
- Payment and tax dry-runs in production-like conditions
- Customer account and order history migration (or a clear transitional plan)
- Rollback criteria and a freeze window everyone understands
“We thought the hard part was themes. The hard part was ten thousand URLs and the emails that started when search traffic dipped.”
Ship a shadow catalog first
Stand up the new catalog and search in parallel. Compare sample journeys: find product → add to cart → checkout start. Fix gaps while the old store still earns revenue.
When organic traffic and conversion on the new stack look trustworthy on a subset of traffic, expand — don't celebrate a Friday night DNS flip.
