--- title: BigCommerce to Shopify migration description: What moves from BigCommerce to Shopify, what you rebuild, and how to keep customers and search rankings at cutover. slug: bigcommerce-to-shopify-migration date: 2026-04-16 updated: 2026-10-02 service: migrations faqs: - question: Can I migrate customer passwords from BigCommerce to Shopify? answer: Plan as if you can't. Customer records, addresses and order history can move, but passwords from some platforms can't. We set up a clean account activation path so returning customers keep their history and set a new password once. - question: What happens to BigCommerce product modifiers on Shopify? answer: They need a decision. Some become Shopify variants, some become metafields or product options handled by an app, and some turn out to be unused. We map each one before import so the catalogue stays manageable. - question: How long does a BigCommerce to Shopify migration take? answer: A focused store can move in weeks. Wholesale pricing, several channels or a redesign running alongside push it towards months. After discovery we give you a clear window and a cutover plan. --- Products, customers, orders and content move from BigCommerce to Shopify. Options, categories, customer groups and channels don't copy straight across. Decide those before import day and the move stays predictable. Teams usually move because the business has changed. They want Shopify Plus, a different set of apps, or a store the team can merchandise every day. ## What moves across cleanly? Most of the core data has a direct home on Shopify. - Products, with titles, descriptions, images and SKUs. - Variants, where they're true stock-keeping options such as size or colour. - Customers and their addresses. - Order history, so returning buyers and your team can still see past orders. - Content pages and blog posts that earn traffic. - The URLs that already rank, mapped to their new Shopify equivalents. That's the base of every migration we run. The data moves into staging first, where we check it against the live store before anyone sees it. ## What needs rethinking on the way in? This is where most of the planning sits. None of it is a problem. It just needs a decision. Options and modifiers. BigCommerce separates options that create variants from modifiers that don't, such as engraving text or a gift message. On Shopify, some become variants. Others become metafields, line item properties or an app. We decide case by case, based on stock, pricing and how customers choose. Categories and collections. A deep category tree becomes Shopify collections plus a navigation menu. It's a good moment to ask which categories customers actually use, and which exist because someone added them once. Custom fields. Product specifications, care details and technical data usually become metafields. That gives your team structured fields to edit, and your theme clean data to display. Customer groups and pricing. If groups drive trade pricing, they map to Shopify B2B companies and catalogues. Since the 2nd of April 2026, [B2B without Plus](/insights/shopify-b2b-without-plus) is an option for simpler wholesale setups. Heavier trade pricing still points to Plus. If your catalogue has outgrown its structure, our guide to [variants or separate listings on Shopify](/insights/variants-or-individual-listings-how-to-organise-your-products-on-shopify) is worth reading before the data mapping starts. ## Channels, apps and checkout Multi-channel setups need a clear structure on Shopify. For each channel, marketplace or feed, we decide what stays native and what an integration should own. Apps get the same treatment. List every app and script on the current store, and write down the job it does. Some jobs become native Shopify features. Some have a strong equivalent in the Shopify App Store. A few need a small custom build. The point is to arrive with a shorter list, not a longer one. Checkout gets scoped early. Payment methods, shipping rules, discount logic and any trade checkout behaviour must be ready on day one. If you're weighing up Plus for checkout control, our note on [whether Shopify Plus is worth it](/insights/is-shopify-plus-worth-it) sets out the questions we ask first. ## How to protect rankings and regular customers A migration protects assets you've already paid for. Search rankings, customer accounts and order history are the three we guard most closely. For search, category and product paths change between platforms. So we crawl the current store, inventory the URLs that earn traffic, and set one-to-one 301 redirects before launch. Blanket redirects to the homepage aren't the plan. After cutover, we watch Search Console and fix gaps quickly. Our guide to [keeping your Google rankings when you move to Shopify](/insights/keep-seo-rankings-shopify-migration) goes deeper. For customers, the priority is continuity. Regular buyers should be able to log in, see past orders and reorder on day one. We rehearse those journeys on staging, including the activation email returning customers receive. ## The stages we follow Every BigCommerce move runs through the same five stages. 1. Audit. The catalogue, channels, apps, integrations and traffic URLs. 2. Map. Data fields, redirects and cutover risks, written down before anything moves. 3. Migrate. Catalogue and customers into staging, cleaned as they land. 4. Rehearse. Redirects, accounts, checkout and top landing pages, tested. 5. Launch and watch. Go live in an agreed trading window, then monitor the first days closely. The length of each stage depends on the data, the channels and whether the storefront is being redesigned at the same time. Many teams take the move as the moment to rebuild the theme too, so clean data doesn't land in a weak design. ## Where Parallel Commerce helps We plan and run [BigCommerce to Shopify migrations](/services/migrations/bigcommerce-to-shopify) as data and SEO projects that happen to launch a Shopify store.
