Shopify Migration
Agency 
ECS® is a Shopify migration agency in London, working with UK brands. We move catalogues, customers, orders, and search equity onto Shopify and Shopify Plus.
Magento to Shopify and BigCommerce to Shopify are scoped as data, a new theme, and redirects. Wix, PrestaShop, Salesforce Commerce Cloud, and WooCommerce follow the same plan.
SHOPIFY MIGRATION
What a Shopify migration includes
A Shopify migration is the catalogue, the customer accounts, the order history, the apps, and the URL map. When the old theme cannot come across, we rebuild it. ECS® runs that as one engagement, from the first export to the week after launch.
Published replatforms include Eat Unique and Nonna Tonda, both Wix stores rebuilt on Shopify. Subscriptions, cut-off rules, and redirects were part of the build. For the engineering after the move, see Shopify development. Ready to scope a platform? Contact the team or read client reviews.
Magento to Shopify migration
A Magento to Shopify migration starts with the catalogue. Configurable products, custom attributes, and customer groups rarely match Shopify one-to-one, so we map them before any import. Customers, order history, and a full 301 redirect map come with the catalogue. The Magento theme stays behind. We design and build the Shopify theme against how the brand sells now, on Shopify or Shopify Plus. B2B price lists and company accounts are scoped up front when the Magento store uses them.
Magento 1 to Shopify migration
Magento 1 stores are usually leaving an unsupported platform. Exports are older, extensions are often abandoned, and the product data needs cleaning before it is safe to import. We treat the export as a one-way archive and rebuild anything an extension was holding together.
Magento 2 to Shopify migration
Magento 2 exports are cleaner, and the store is often still trading. We build Shopify in parallel, import in passes, and cut over on a planned window so the live Magento 2 site keeps taking orders until DNS moves.
BigCommerce to Shopify migration
A BigCommerce to Shopify migration is a catalogue and content move plus a theme rebuild. Product options, metafields, customer accounts, and blog URLs need a map. We rebuild the storefront on Shopify rather than forcing a BigCommerce theme into Liquid, and we replace apps that have no Shopify equivalent before launch.
Wix to Shopify migration
Wix stores come across as a rebuild. Products and customers can move. The Wix layout cannot. Eat Unique and Nonna Tonda were both Wix to Shopify migrations, including subscription logic where the brand needed it.
PrestaShop to Shopify migration
PrestaShop catalogues, combinations, and customer accounts export into a map we agree before import. Module behaviour that has no Shopify app is rebuilt or dropped. Redirects cover category and product URLs so the old PrestaShop paths resolve.
Salesforce to Shopify migration
A Salesforce Commerce Cloud move is a replatform, not a theme swap. We take the catalogue, price books, and customer data that should live in Shopify or Shopify Plus, and we rebuild the storefront. Integrations that stay outside Shopify are listed in discovery so nothing is assumed to transfer.
Moving from WooCommerce? The WooCommerce to Shopify guide covers the decision and the runbook. We can run that migration with you.
