BigCommerce to Shopify Migration

LitExtension can migrate supported BigCommerce data such as products, product images, SKUs, prices, inventory, variants, custom fields, categories, customers, customer addresses, store credit, historical orders, coupons, CMS pages, blog posts, and SEO metadata.

The exact fields available depend on how the data is stored in BigCommerce and whether Shopify has a corresponding field or data structure. Run a Free Demo Migration to verify the product catalog, customer profiles, order history, URLs, images, and field mapping before transferring the complete store.

Yes. Your existing BigCommerce storefront can remain available to customers while LitExtension reads and transfers the selected data to your Shopify store through a secure API connection.

Before launch, you should run a final data update, validate inventory and newly created orders, test your Shopify checkout, and then switch your domain during a controlled cutover window. This helps minimize disruption without making an absolute uptime guarantee.

Start by recording the number of products, variants, customers, orders, categories, pages, and blog posts in your BigCommerce store.

Export a recent backup before removing duplicate records, discontinued products, broken images, outdated content, or other unnecessary data.

You should also document your current URLs, payment gateways, shipping rules, tax settings, apps, custom fields, and third-party integrations.

Prepare the corresponding Shopify settings and avoid major catalog restructuring while the migration is running.

A platform migration can cause temporary changes in organic traffic and keyword rankings because BigCommerce and Shopify use different URL structures.

LitExtension can migrate supported SEO metadata and create 301 redirects from old BigCommerce URLs to the corresponding Shopify product, collection, page, and blog URLs.

Before launch, test important redirects, update internal links, review canonical tags and metadata, submit the Shopify sitemap to Google Search Console, and monitor indexing and crawl errors after the migration.

LitExtension maps supported BigCommerce product options and variant combinations to Shopify product options and variants. Custom product information may be transferred into suitable Shopify fields or metafields, depending on the source structure and your migration configuration.

Shopify currently supports up to three options and 2,048 variants per product. Products with more complex modifiers, conditional options, custom pricing rules, or unsupported combinations may need restructuring, a product options app, or customized data mapping.

Payment gateway credentials, shipping configurations, tax rules, fulfillment locations, and carrier settings generally need to be configured separately in Shopify because they are tied to each platform and merchant account.

Before launch, activate your Shopify payment provider, configure shipping zones and rates, review tax settings, connect fulfillment services, and place test orders using different products, addresses, discounts, shipping methods, and payment options.

An automated migration app is suitable for small to medium-sized stores with standard products, customers, orders, categories, and limited custom data. It gives you more control over the BigCommerce to Shopify migration process and is generally the more cost-effective option, but you will need to configure the migration, review the data mapping, and validate the Shopify store yourself.

An expert migration service is better suited to large or complex stores with extensive product catalogs, custom fields, B2B data, SEO redirects, multilingual content, Shopify Plus requirements, or third-party integrations. Migration specialists handle the technical setup, custom data mapping, quality assurance, recent data migration, and post-migration checks, reducing the workload and technical risk for your team.

To migrate data from BigCommerce, LitExtension requires a store-level V2/V3 API token and the API Path generated in your BigCommerce control panel.

Set the required resources to Read-only, including Content, Customers, Information & Settings, Marketing, Orders, Products, Channel Settings, and Channel Listings, so LitExtension can retrieve the selected data without modifying your live BigCommerce store.

BigCommerce B2B data may be migrated to Shopify Plus, but it normally requires a technical assessment because the two platforms structure wholesale data differently.

Company accounts, customer groups, price lists, catalogs, payment terms, quote workflows, tax exemptions, and purchasing permissions might require custom mapping or redevelopment.

Document your existing B2B workflows and integrations before migration so the team can determine which records can be transferred directly, which should be stored in Shopify metafields, and which functions need Shopify Plus B2B features or a third-party app.

Compare the entity counts in BigCommerce and Shopify, then inspect a representative sample of products, variants, SKUs, images, prices, inventory, customer addresses, historical orders, coupons, pages, blog posts, and SEO metadata.

Also test collection assignments, search and filters, customer account access, discount codes, payment methods, shipping rates, taxes, email notifications, mobile pages, checkout, and 301 redirects.

Complete these checks before connecting your production domain and opening the Shopify store to customers.

Yes. A Free Demo Migration transfers a representative sample of your BigCommerce data so you can review products, variants, customers, orders, images, field mapping, and formatting in Shopify before purchasing a full migration.

Free Demo Migration is different from Free Migration. LitExtension currently offers unlimited free demos, while stores with up to 100 qualifying entities may be eligible for a complete Free Migration.

No. Customer passwords are encrypted and cannot normally be migrated from BigCommerce to Shopify.

With Shopify Customer Accounts, imported customers sign in using their email address and a one-time six-digit verification code, so no password reset is required.

Stores using legacy customer accounts must invite customers to create a new password. Supported customer profiles, contact details, addresses, and related order records can still be transferred based on the selected migration configuration.

Your BigCommerce store can continue receiving orders and customer registrations while the initial migration runs.

However, records created or edited after the initial data snapshot are not automatically included in the completed migration.

Before switching your domain to Shopify, use Recent Data Migration to transfer newly created records and Smart Update to synchronize supported changes made to existing data.

Compare entity counts, order totals, customer records, and inventory levels before completing the final cutover.

BigCommerce uses product categories and subcategories, while Shopify organizes products through collections, product tags, menus, and collection conditions. Because these structures are different, category relationships cannot always be transferred one to one.

LitExtension can migrate BigCommerce categories and use product tags to create Shopify collections that preserve the main product grouping. You should still review nested navigation, collection conditions, product assignments, category descriptions, images, and SEO URLs before launch.

Yes. LitExtension supports the migration of historical order information, including order dates, statuses, customer details, billing information, products, SKUs, quantities, taxes, discounts, subtotals, and order totals.

The Preserve Order IDs option can retain supported BigCommerce order identifiers in Shopify for easier reference and customer service.

Because imported historical orders can behave differently from orders created natively in Shopify, review a representative sample and confirm the relationships between products, customers, and orders before launch.

These data types require separate compatibility checks because they might be stored by a BigCommerce app or use a structure that Shopify does not support natively.

Product reviews may require a compatible Shopify review app, while gift certificates, loyalty balances, subscriptions, wishlists, and other app-specific records may need customized migration.

Provide a list of your BigCommerce apps and advanced data types before migration so LitExtension can identify the supported entities, required Shopify apps, and any custom mapping work.

Pricing is based on the number of entities you need to migrate, such as products, customers, orders, and related data.

The automated migration tool starts from $59 and is free for stores with fewer than 100 entities. For example, a store with around 5,000 entities typically costs about $169 using the automated tool.

Expert-led migration service starts from $169, and larger or more complex stores (for example, around 5,000 entities) may cost around $500 depending on requirements.

Customers can check exact pricing in the pricing section before starting the migration. For merchants who prefer a fully managed experience, the All-in-One Migration Package includes a dedicated migration specialist, advanced configuration options, and 60 days of post-migration support, all at a fixed price.

The data transfer time depends on your entity volume, product variants, images, historical orders, API processing limits, additional options, and custom mapping requirements.

A standard store may complete the automated transfer relatively quickly, while a large catalog, B2B store, or Shopify Plus project usually requires more preparation and validation.

Run a Free Demo Migration to inspect the mapping quality and ask for a scoped timeline when your store includes custom fields, multiple languages, complex product options, ERP connections, or other integrations.

No. BigCommerce themes, template code, installed apps, and platform-specific customizations cannot be transferred directly because Shopify uses a different theme architecture, app ecosystem, and storefront framework.

You will need to select or develop a Shopify theme, rebuild the required page layouts, and replace your BigCommerce apps with Shopify alternatives.

Review functionality such as product filters, subscriptions, reviews, loyalty programs, search, bundles, shipping integrations, ERP connections, and custom checkout logic before beginning the migration.

Yes. Migrating your products, customers, orders, and content does not automatically move or connect your domain to Shopify.

Keep the domain pointed to your BigCommerce store while you build and test Shopify. After validating the migrated data, checkout, integrations, and 301 redirects, connect or transfer the domain to Shopify and update the required DNS records as part of the final launch process.
