BigCommerce to Shopify: A Migration Guide From Someone Who Has Done It

BigCommerce merchants are not confused about whether Shopify is bigger. They already know. What they do not know, and what no platform comparison chart ever tells them, is exactly which parts of their existing store will survive the move, and which parts will need to be rebuilt from scratch.

That distinction matters. A lot.

Having run migrations from BigCommerce to Shopify since 2016, across industries and catalog sizes, here is the honest breakdown of what actually changes under the hood, where merchants get surprised, and what to plan for before you touch a single CSV file.

Your product options model is about to change

BigCommerce is unusually generous with native product options. Modifier sets, file uploads, text inputs, required fields, all configurable at the product level, no apps required. That flexibility is baked into the platform.

Shopify works differently. Its core variant model supports up to three options per product (think size, color, material) with a hard ceiling of 100 variants per listing. For a standard DTC apparel brand, that ceiling is invisible. For anyone selling configurable goods, custom kits, made-to-order products, or technical items with deep option trees, you will hit it fast, and you will need a plan before you get there.

The two main paths are third-party apps like Infinite Options or Wide Bundles, or pushing complex configuration logic into metafields. Shopify metafields have matured significantly and are now accessible natively through the Storefront API. You can define typed content, reference objects, and expose values in themes without handwriting Liquid. But the key word is "typed." If BigCommerce custom fields were used to store structured data as plain text strings, a common pattern, the migration is an opportunity to define proper metafield types (integer, date, boolean, product reference, and more). That is more work upfront. It is also a substantially cleaner data architecture on the other side.

One thing worth noting for merchants arriving from Magento: the EAV database structure makes attribute export genuinely painful, and remapping to a new platform is frequently a bespoke engineering project. BigCommerce custom field structure is simpler. The Shopify metafield mapping process is methodical, not architectural. That is a meaningful difference.

Native faceted search does not transfer

BigCommerce includes native faceted search tied directly to product options and custom fields. Merchants who built their filter UX on that foundation often do not realize how much they depend on it until they try to replicate it on Shopify.

Shopify native collection filtering handles availability, price, and variant options cleanly. It does not natively support filtering on metafields or custom product attributes without developer work. For brands where customers filter by material, compatibility, or technical specification, that gap is not minor.

Two paths exist. Shopify Search and Discovery is free, integrates well with the Storefront API, and handles basic faceted filtering adequately. For AI-powered relevance, synonym management, or heavily customized filter logic, third-party solutions like Boost Commerce, Searchanise, or Klevu add cost and real capability. Budget for one before go-live. This is not a post-launch enhancement. It is a pre-launch requirement.

Multi-currency: BigCommerce did this natively before Shopify did

BigCommerce has offered native multi-currency support since 2019. It handles display, conversion, and transactional processing within the platform, with no additional layer of configuration. For B2B sellers running global operations, that was a legitimate advantage and, for years, a real differentiation point.

Shopify answer is Shopify Markets, launched in 2022 and significantly expanded since. Markets lets merchants manage multiple countries from a single store: localized pricing, market-specific domains or subfolders, language settings, currency conversion, per-market price adjustments. With Shopify Payments enabled, merchants can sell in over 130 local currencies with automatic exchange rate updates.

The caveat that matters: Shopify Payments is required for multi-currency checkout. Shopify Payments is currently available in 23 countries. Merchants operating outside those markets, or running a third-party payment gateway, will need an app to bridge the gap. That is a configuration decision to make during scoping, not one to discover during QA week.

Shopify Markets Pro, powered by Global-e, adds managed duties, tax compliance, and international logistics. Transaction fees run 3.25% to 3.5% depending on plan tier. For merchants with meaningful international revenue, that cost line needs to go into the migration business case before anyone signs a statement of work.

The URL architecture difference will cost you if you ignore it

This is the part of BigCommerce-to-Shopify migrations where the most unnecessary SEO damage happens. The two platforms use fundamentally different URL structures, and if a complete redirect map is not in place at DNS cutover, years of ranking equity return 404s.

BigCommerce uses patterns like /category-name/ for categories and various product slug formats depending on store configuration. Shopify uses /collections/ for collections and /products/ for product pages. Full stop. Every indexed URL from the previous store needs a 301 mapped to its Shopify equivalent.

Shopify supports bulk 301 redirect uploads via CSV. For a catalog with hundreds or thousands of SKUs, building that map is a project in itself. The sequence: export the full URL list from BigCommerce (products, categories, blogs), map each URL to its Shopify destination, validate the map, import before DNS cutover. Do not flip DNS and test redirects simultaneously.

Blog URL structures are their own footnote. BigCommerce uses /blog/ as the base path. Shopify uses /blogs/ with a named blog handle, /blogs/news/ for example. If content marketing is driving meaningful organic traffic, those paths need their own redirect entries. Missing them is a common and completely avoidable mistake.

The good news: Shopify handles canonical tags, hreflang for international stores, and sitemap generation automatically. The technical SEO infrastructure is there. The redirect layer is the one thing that has to be built manually, and it has to be right before go-live.

What a real migration scope actually looks like

A recent project at Shugert started as a "standard" BigCommerce migration for a specialty retailer. Multi-language SEO footprint, deep product option tree, wholesale pricing rules for B2B accounts. Within the first audit, it was clear this was a multi-phase engagement. Not because the platform could not support it, but because matching what a mature BigCommerce store was already doing natively required deliberate configuration work on Shopify.

Phase one: redirect architecture. Phase two: metafield definition and data migration using Matrixify. Phase three: filter rebuild with Shopify Search and Discovery plus a custom Liquid layer. Phase four: Shopify Markets configuration for three selling regions.

The store landed in better structural shape than it left. The timeline was longer than the client initial estimate. That is almost always the story. Migrations at this level are architecture projects, not data-transfer tasks. The tools exist. Getting them configured correctly takes real expertise and real time.

The bottom line

Shopify can do what BigCommerce can do. The ecosystem is larger, the developer talent pool is deeper, and the platform roadmap, from Hydrogen headless builds to Shopify Markets Pro international logistics, is aggressive.

But the platform gap is real in a few specific places: native product configurability, native faceted search, and multi-currency without Shopify Payments. Each one has a solution. None of them is automatic.

For DTC and B2B brands on BigCommerce weighing the move, the question is not whether Shopify is capable. It is whether the migration is scoped correctly. At Shugert, our Shopify migration and replatforming work is built around exactly this kind of scoped approach: catalog architecture, full redirect mapping, filter rebuild, and Markets configuration, so merchants arrive on Shopify with their SEO equity intact, their performance optimized, and their CRO fundamentals in place.
