BigCommerce to Shopify Migration Guide

Why brands move from BigCommerce to Shopify, what the migration actually involves, and how to protect SEO and multi-channel integrations along the way.

By UVT Team

A BigCommerce to Shopify migration moves your products, customers and order history onto Shopify's platform, replaces BigCommerce's built-in and app functionality with Shopify's app ecosystem, and redirects every indexed URL so search rankings carry over. Most BigCommerce migrations take 6 to 12 weeks, similar to a WooCommerce migration — the platforms are structurally closer to each other than either is to Magento.

Key takeaways

BigCommerce and Shopify are both fully-hosted SaaS platforms, so a migration is mostly a data and functionality move, not an infrastructure one — timelines are usually 6–12 weeks.
BigCommerce's larger built-in feature set (multi-currency, product filtering, some B2B tools) means part of the migration work is deciding which Shopify app replaces each native feature.
Shopify's app ecosystem is significantly larger than BigCommerce's, which is the main reason brands move — more options, more frequent updates, more specialized tools per use case.
BigCommerce's API-first, headless-friendly architecture is a real strength some brands give up moving to Shopify's theme model — worth weighing honestly if headless commerce is a priority.
URL structures differ enough between the platforms that a full redirect map is still essential, even though both platforms are conceptually similar.

Why brands move from BigCommerce to Shopify

BigCommerce is a capable platform, and brands don't usually leave because something is broken — they leave because Shopify's ecosystem has grown larger and more specialized. More apps means more options for any specific problem (subscriptions, bundling, personalization, loyalty), more frequent updates from a larger developer community, and an easier time hiring talent who already know the platform. Some brands also move for Shopify Plus specifically: checkout extensibility, a larger partner and agency network, and a more mature B2B offering at the Plus tier.

What moves in a BigCommerce to Shopify migration

Products and variants. BigCommerce's product and variant model maps reasonably cleanly to Shopify's, though BigCommerce's more flexible option sets occasionally need restructuring for Shopify's stricter variant limits.
Customers. Profiles, addresses and order history move; as with any migration, passwords need a reset flow rather than a direct transfer.
Multi-currency and multi-storefront setups. BigCommerce's native multi-storefront tools typically map to Shopify Markets or separate Shopify Plus expansion stores, depending on how distinct each storefront needs to be.
Built-in features that need a Shopify app. Advanced product filtering, some promotion types, and certain B2B tools that are native to BigCommerce usually need a specific Shopify app replacement, not a Shopify-native equivalent — plan this list before development starts.
Content. Pages and blog posts migrate; any BigCommerce page-builder content needs rebuilding as Shopify sections.

Protecting SEO in a BigCommerce to Shopify migration

BigCommerce and Shopify use different default URL structures, so the same redirect discipline applies as any other migration:

Export every indexed URL from Google Search Console, including any custom URL structures BigCommerce allowed that Shopify doesn't support directly.
Map each one to its Shopify equivalent — products to /products/, categories to /collections/ — redirecting discontinued items to the closest live collection.
Carry over title tags, meta descriptions and structured data for top-performing pages.
Resubmit your sitemap in Search Console on launch day and monitor Coverage weekly for a month.

BigCommerce vs. Shopify: what's genuinely different

Two things are worth being honest about before migrating:

Checkout. BigCommerce's standard checkout is more customizable out of the box than standard Shopify's. If deep checkout customization matters to your business, that's a strong argument for Shopify Plus (Checkout Extensibility) rather than standard Shopify.
Headless and API flexibility. BigCommerce was built API-first and is genuinely strong for headless commerce. Shopify's Storefront API and Hydrogen framework are a real answer here, but if your BigCommerce setup is already headless and working well, that's a deliberate architecture decision worth weighing on its own terms, not assuming Shopify is automatically better.

What a BigCommerce to Shopify migration costs

Cost scales with catalogue size, how many BigCommerce-native features need a specific app replacement, and theme customization. Because both platforms are fully hosted, the infrastructure and hosting-cost argument that drives some Magento and WooCommerce migrations doesn't apply the same way here — the case for moving is more often ecosystem and app availability than cost-of-ownership. Ask for an itemized quote covering data migration, app replacements, theme build and QA rather than a single lump figure.

Frequently Asked Questions

How long does a BigCommerce to Shopify migration take?

Most BigCommerce to Shopify migrations take 6 to 12 weeks from discovery to launch, similar to a WooCommerce migration — both platforms are fully hosted, so there's no infrastructure layer to untangle, but functionality mapping still takes real planning.

Will I lose SEO rankings moving from BigCommerce to Shopify?

Not if every indexed URL is mapped to a 301 redirect and your top pages keep their titles, meta descriptions and structured data. A brief ranking dip while Google re-crawls is normal and typically recovers within 4–8 weeks with a complete redirect map.

What happens to BigCommerce's built-in multi-currency and B2B features?

Multi-currency typically maps to Shopify Markets. B2B features vary: Shopify Plus has native company accounts and custom pricing that replace much of what's built into BigCommerce, but specific workflows may need a Shopify app or custom logic — this should be mapped during planning, not discovered mid-build.

Is Shopify better than BigCommerce, or just different?

Both are capable, fully-hosted ecommerce platforms. The honest reasons brands move are usually Shopify's larger app ecosystem, bigger agency and talent pool, and Shopify Plus's checkout and B2B capabilities — not that BigCommerce is broken. If your store relies heavily on BigCommerce's native checkout customization or headless architecture, that trade-off deserves real consideration before committing to a migration.

Can I migrate from BigCommerce to Shopify without downtime?

Yes. The new store is built and tested in a password-protected environment while the current store stays live, then the switch (DNS and final data sync) happens during a low-traffic window — typically a few minutes of effective downtime, not hours.
