How long does an ecommerce replatform take?

Three to seven months for most mid-market brands. The range depends on catalog size, the number of integrations, how much custom functionality needs rebuilding and how clean the existing data is.

Will we lose SEO rankings when we replatform?

Some short term movement is normal, but a lasting drop is avoidable. A full redirect map, preserved metadata and content, and close monitoring after launch keep rankings and organic traffic stable in a well planned migration.

Can customer accounts, passwords and subscriptions be migrated?

Customer records, order history and subscriptions can be migrated. Passwords usually cannot, because platforms store them in a form that cannot be transferred. Customers are invited to activate their account on the new store, and we plan that communication so it feels like part of the launch rather than a problem.

Which platform should we move to?

It depends on your catalog, channels, customer types and team. We work across Shopify Plus, BigCommerce and composable stacks, and recommend based on fit. If the choice is not yet clear, an ecommerce strategy and roadmap settles it before migration work starts.

Do we have to stop trading during the migration?

No. The old store keeps trading until cutover, a final data sync brings across the latest orders and customers, and the switch is planned for a quiet trading window. Most customers will notice nothing other than the new site.

Replatforming moves your store from one commerce platform to another. The visible part is a new storefront. The hard part is everything underneath it, including years of products, customers, orders, subscriptions, URLs and integrations that all need to arrive intact.

Done well, customers notice a better site and nothing else. Done badly, search traffic drops, subscriptions fail and the team spends months cleaning up. Most of the difference comes down to planning and data work done well before launch.

We confirm a replatform is the right move

Not every frustration with a platform needs a new one. Before scoping a migration we check whether the problem is the platform itself or the apps, theme and processes around it. If you are unsure, our article on the clues it is time to replatform covers the signals worth looking for.

We treat data as the main project

Product, customer, order and subscription data is mapped field by field, cleaned and migrated in repeated test runs long before launch. Variants, metafields, customer tags, order history and loyalty balances are each checked against the source. Problems found in a test run are cheap. Problems found after launch are not.

We protect your search rankings

Every indexed URL gets a redirect plan. We carry over page titles, descriptions, structured data and content, and we benchmark rankings and organic traffic before launch so any change afterwards is caught and fixed quickly.

We rebuild the integrations properly

ERP, inventory, tax, shipping, email, reviews and subscription tools all connect differently on a new platform. We use the migration to remove integrations you no longer need and replace fragile ones, rather than copying old problems across. For brands running NetSuite, the ERP connection is usually where most of the planning goes.

We launch without stopping trade

Cutover is planned around your trading calendar, away from peak periods and major promotions. A final data sync, a tested launch checklist and a rollback plan keep the store taking orders, and the team stays on hand through launch and the weeks after it.
