BigCommerce to Shopify Migration Guide

BigCommerce and Shopify serve similar merchant profiles, which makes migration between them more straightforward than migrating from Magento or WooCommerce. The platforms have comparable product data models, similar URL structures, and overlapping app ecosystems. A well-planned BigCommerce to Shopify migration completes in 3–6 weeks for most stores with minimal disruption.

The migration decision is usually triggered by: Shopify's superior Shopify Plus offering for enterprise growth, ecosystem maturity (more developers, more apps), superior checkout customization through Checkout Extensibility, or simply a consolidation to Shopify if other brands in a portfolio already use it.

Key Takeaways

• BigCommerce's product data model is more similar to Shopify than Magento or WooCommerce, simplifying data migration
• The main structural difference: BigCommerce allows product variants with many options; Shopify limits to 3 options and 100 variants
• URL structures are similar but not identical — 301 redirects still required for all changed URLs
• BigCommerce's native shipping features (real-time rates, ShipperHQ integration) are matched by Shopify's shipping infrastructure
• BigCommerce's B2B features (customer groups, tiered pricing) map well to Shopify B2B on Plus
• Multi-channel (Amazon, eBay, Facebook) integrations have equivalent Shopify apps
• Average migration timeline: 3–6 weeks for stores under 10,000 SKUs
• API rate limits differ significantly — plan around Shopify's 2 requests/second limit (burst to 40) for large catalogs

BigCommerce vs. Shopify: Feature Parity Analysis

Before migration, understand which BigCommerce features have direct Shopify equivalents and which require workarounds:

The 3-option/100-variant limit is BigCommerce merchants' most common concern. BigCommerce allows unlimited product options and variants (though performance degrades above ~600 variants). Assess your catalog before migration.

Phase 1: Pre-Migration Audit (Week 1)

Catalog Analysis

Export your BigCommerce catalog via Catalog → Export. Analyze the export for:

Current URL Audit

BigCommerce URL structures:

BigCommerce uses trailing slashes; Shopify does not. Every URL requires a redirect even if the slug is identical.

App and Integration Inventory

Many popular ecommerce apps support both BigCommerce and Shopify. For these, migration is as simple as disconnecting from BigCommerce and reconnecting to your Shopify store — settings and historical data may transfer automatically.

---

Phase 2: Data Export from BigCommerce

BigCommerce provides several export paths:

Products Export

From BigCommerce Dashboard → Products → Export Products. Choose the "Default" template which includes all product fields, or create a custom template to include specific custom fields.

The export CSV includes:

• Product name, SKU, description
• Price, sale price, cost price
• Product type, brand, categories
• Images (as URLs)
• Variants (size, color, etc.)
• Custom fields
• SEO meta title and description
• Product weight and dimensions

Customers Export

BigCommerce → Customers → Export Customers. The export includes:

• First name, last name, email
• Phone number
• Stored addresses
• Customer group assignment
• Date created

Note: Customer passwords are hashed and cannot be exported in a reusable format. Customers will need to reset passwords on Shopify. Implement a password reset email campaign as part of your migration communication plan.

Orders Export

BigCommerce → Orders → Export Orders. This exports historical order data for record-keeping and customer service purposes. Shopify imports this as "legacy" orders — visible in order history but not processed as active orders.

---

Phase 3: Shopify Data Import

Using Litextension for Automated Migration

Litextension connects directly to your BigCommerce store API and Shopify Admin API to migrate:

• Products with variants, images, and SEO data
• Customer accounts
• Order history
• Product categories → Shopify collections (smart and manual)
• Product reviews (via Judge.me or Stamped.io integration)
• Discount codes

BigCommerce to Shopify is one of Litextension's cleanest migrations due to platform similarity. Typical accuracy: 98–100% for core product and customer data.

Manual Import via Shopify CSV

For merchants comfortable with data manipulation, Shopify's product CSV template accommodates most BigCommerce export fields directly:

Handling Brand Pages

BigCommerce has native Brand pages. Shopify doesn't have a built-in brand entity. Options:

• Create a Shopify Collection per brand with brand-specific products
• Create brand pages as Shopify Pages using a theme template
• Use Shopify Metaobjects (launched 2022) to create a structured "Brand" entity type

For SEO purposes, redirect BigCommerce brand URLs to the corresponding Shopify collection. This preserves any link equity from brand pages indexed by Google.

---

Phase 4: URL Redirect Configuration

Even with similar URL structures, the differences between BigCommerce and Shopify require comprehensive redirects.

Automated Redirect Generation Script

Export your BigCommerce sitemap (available at yourdomain.com/sitemap.xml). Parse the sitemap to extract all indexed URLs. Compare with Shopify handles (generated during data migration) to build the mapping:

BigCommerce URL → Shopify URL
/running-shoes/ → /products/running-shoes (no trailing slash)
/footwear/ → /collections/footwear
/blog/shoe-care-guide/ → /blogs/news/shoe-care-guide
/about-us/ → /pages/about-us

Generate a Shopify redirect CSV from this mapping and bulk import via Admin → Online Store → Navigation → URL Redirects → Import.

Canonical URL Configuration

After migration, verify that Shopify's canonical tags point to the correct URLs. Shopify automatically adds canonical tags — confirm they reference your custom domain, not {storename}.myshopify.com.

---

Phase 5: BigCommerce-Specific Features Requiring Special Handling

Multi-Storefront → Shopify Expansion Stores

BigCommerce's multi-storefront feature allows running multiple branded storefronts from one backend. Shopify Plus offers expansion stores as the equivalent — each expansion store is a separate Shopify store with its own theme, domain, and checkout, but all managed under one Plus subscription.

Migration path: Each BigCommerce storefront becomes a separate Shopify expansion store. Product catalog sync between expansion stores requires a third-party app (Excelify, Syncio) or custom API integration.

BigCommerce Promotions → Shopify Discounts

BigCommerce's promotions engine supports complex conditional logic:

Complex BigCommerce promotions with multiple conditions may not have a direct Shopify equivalent and may need to be simplified or rebuilt as Shopify Functions (custom discount logic, available on Shopify Plus).

BigCommerce Faceted Search → Shopify Storefront Filters

BigCommerce includes built-in faceted search with multiple filter types. Shopify's native collection filters support:

• Product tag filtering
• Product type filtering
• Availability filtering
• Price range filtering
• Variant option filtering (color, size)

For more sophisticated filtering (multi-select facets, filter by product metafield), apps like Boost Commerce or Searchpie replicate BigCommerce's faceted search capability.

---

Phase 6: Shopify Theme Configuration

BigCommerce themes don't convert to Shopify — you'll build or purchase a new Shopify theme.

Theme Selection for BigCommerce Migrants

Consider your BigCommerce theme's key features and find Shopify equivalents:

Shopify 2.0 Section Architecture

Unlike BigCommerce's page builder, Shopify uses a sections/blocks architecture. Every homepage section (hero, featured collections, testimonials, etc.) is a self-contained, drag-and-drop block. This is more constrained than page builders but produces significantly faster pages because sections are server-side rendered, not JavaScript-built at runtime.

Frequently Asked Questions

Is BigCommerce to Shopify easier than WooCommerce to Shopify?

Generally yes. BigCommerce and Shopify have more similar data models than WooCommerce and Shopify. The platforms share comparable product structures, customer schemas, and order formats. The main complications are the variant limits (BigCommerce is more permissive), URL redirects (trailing slash differences), and any BigCommerce-specific features like multi-storefront that require a Plus-level Shopify solution.

Can I keep my BigCommerce SEO rankings during migration?

Yes, with comprehensive 301 redirects and correct canonical tag implementation. The biggest risk factor is the trailing slash difference (BigCommerce uses /category/, Shopify uses /collections/category). Ensure every URL in your BigCommerce sitemap has a corresponding 301 redirect in Shopify. Monitor Google Search Console for 404 errors weekly during the first 60 days.

What happens to my BigCommerce reviews and UGC?

BigCommerce's native review system data can be exported and imported to Shopify review apps (Judge.me, Stamped.io, Yotpo). If you're already using a third-party review app on BigCommerce (Yotpo, Okendo), simply reconnect the app to your Shopify store — your historical reviews are stored in the review platform, not BigCommerce, and carry over automatically.

How do I migrate my BigCommerce customer accounts?

Customer account data (name, email, address book, order history) migrates fully. Customer passwords cannot transfer due to different hashing systems. Schedule a bulk password reset email campaign to go out 24 hours after migration, framed positively: "We've upgraded our store — set your new password to continue shopping." Most customers complete this within 48–72 hours.

Should I switch to Shopify Payments from my current BigCommerce payment processor?

Shopify Payments (available in US, UK, Canada, Australia, and 15+ other countries) offers the lowest transaction fees on Shopify: 0% transaction fee plus Stripe processing rates. Third-party processors incur an additional 0.6% (Advanced) or 0.5% (Plus) transaction fee. For most merchants, switching to Shopify Payments at migration reduces payment processing costs. However, evaluate your current processor's rates carefully if you've negotiated custom interchange-plus pricing.
