BigCommerce to Shopify Migration Services

If you’re evaluating a BigCommerce to Shopify migration, you’re likely running into the same friction points a lot of growing merchants hit: rigid theme customization, clunky app integrations, or a platform that no longer matches where your business is headed. Turnaround Commerce specializes in migrating stores from BigCommerce (along with WooCommerce and Magento) onto Shopify and Shopify Plus, handling the technical, structural, and SEO-sensitive work required to move a live store without losing revenue, rankings, or historical data along the way.

A migration between platforms is not a simple export-import job. BigCommerce and Shopify structure products, variants, URLs, metafields, and customer data differently, which means a naive migration can quietly break things that don’t show up until weeks later — abandoned cart flows, broken product filters, orphaned redirect chains, or duplicate content issues that erode organic traffic. This page walks through how we approach a BigCommerce to Shopify migration, what typically needs attention, and what to expect from the process.

Why Merchants Move From BigCommerce to Shopify

There isn’t one universal reason merchants initiate a BigCommerce to Shopify migration, but a few patterns show up consistently:

• App and theme ecosystem. Shopify’s app marketplace and theme development ecosystem is significantly larger, which matters once you want more granular control over merchandising, subscriptions, or checkout customization (available on Shopify Plus).
• Front-end flexibility. Merchants wanting more control over performance and design often move toward Shopify because of the maturity of its theming architecture and, for larger brands, the option to go headless with Hydrogen/React.
• Operational scaling. As order volume grows, merchants often want tighter native integrations with ERP, CRM, and marketplace channels like Amazon — areas where Shopify’s ecosystem tends to offer more mature tooling.
• Checkout and conversion control. Shopify Plus in particular gives larger merchants more flexibility over checkout customization than BigCommerce typically allows at comparable price points.

Whatever the underlying reason, the technical challenge is the same: move everything that matters — products, variants, customers, orders history, content, and URL equity — without disrupting the store’s ability to convert or rank.

What a BigCommerce to Shopify Migration Actually Involves

A structured migration is built around a few distinct phases. Skipping or rushing any of them is usually where post-launch problems originate.

1. Audit and Data Mapping

Before anything moves, we map how your BigCommerce store’s data model translates to Shopify’s. This includes product catalogs, variant structures (BigCommerce and Shopify handle variant limits and option sets differently), customer records, order history, discount codes, and any custom fields or metafields that power your product pages, filtering, or personalization.

2. URL Structure and Redirect Planning

This is one of the most consequential and most frequently underestimated parts of any BigCommerce to Shopify migration. BigCommerce and Shopify generate URLs differently by default — for products, collections, and blog content. Without a deliberate redirect strategy, you risk breaking inbound links, losing indexed pages, and creating 404s that hurt both user experience and organic visibility. We build a full URL mapping plan and 301 redirect strategy before launch, not after.

3. Theme and Front-End Rebuild

Your BigCommerce theme doesn’t transfer — it has to be rebuilt on Shopify’s Liquid templating framework (or as a headless Hydrogen build, for merchants who want that architecture). This is an opportunity to fix long-standing UX issues, improve Core Web Vitals, and rebuild key templates — product, collection, cart — with performance in mind rather than simply replicating what existed before.

4. App and Integration Rebuild

Apps and integrations tied to your BigCommerce store — reviews, subscriptions, loyalty, tax, shipping — need Shopify-native equivalents or custom rebuilds. For merchants with custom ERP or CRM connections, or Shopify-Amazon sync needs, this phase often takes the most technical planning since off-the-shelf apps don’t always cover custom business logic.

5. Content, SEO, and Metadata Migration

Page titles, meta descriptions, structured data, blog content, and image alt text all need to move over intact — and ideally get audited in the process. This is also when we implement redirects, verify canonical tags, and check that Shopify’s default SEO settings (which differ from BigCommerce’s) aren’t creating duplicate content issues.

6. Staged Testing

Before go-live, the store is tested in a staging environment: checkout flows, payment gateways, shipping rules, tax calculation, discount codes, and customer account access. Testing on real order scenarios rather than just visual QA is what catches issues before customers do.

7. Launch and Post-Migration Monitoring

After cutover, we monitor crawl behavior, redirect performance, and site speed to catch anything that surfaces once real traffic and search engines interact with the new store. Migrations aren’t “done” the moment the new site goes live — the days and weeks after launch are when redirect gaps or indexing issues tend to show up.

SEO Considerations Specific to BigCommerce to Shopify Migrations

SEO risk is the single biggest concern we hear from merchants considering a BigCommerce to Shopify migration, and it’s a legitimate one. Moving platforms changes URL structures, template markup, page speed characteristics, and sometimes internal linking patterns — all signals search engines use. The goal of a well-executed migration isn’t to promise a specific ranking outcome (no legitimate agency can guarantee that), but to minimize unnecessary disruption through:

• Comprehensive 301 redirect mapping from old BigCommerce URLs to new Shopify URLs
• Preserving or improving existing page titles, meta descriptions, and header structure
• Maintaining structured data (schema markup) for products and reviews where applicable
• Monitoring crawl errors and indexation in the weeks following launch
• Improving Core Web Vitals and page speed, since Shopify’s infrastructure and theme optimization can often outperform a poorly optimized BigCommerce build

Done carefully, a migration is an opportunity to clean up years of SEO debt — orphaned pages, thin content, slow templates — rather than just a lateral move.

How Long Does a BigCommerce to Shopify Migration Take?

Timelines vary significantly based on catalog size, the number of custom integrations, and whether you’re moving to standard Shopify or Shopify Plus with custom checkout requirements. A smaller catalog with minimal custom app logic moves faster than a store with thousands of SKUs, complex variant structures, and multiple ERP or CRM integrations. Rather than quote a generic timeline that doesn’t reflect your actual setup, we typically start with a scoped audit of your BigCommerce store to give a realistic project timeline based on what’s actually involved.

What to Prepare Before You Migrate

Merchants who move through the process most smoothly tend to have a few things ready ahead of time:

• Admin access to your current BigCommerce store and any connected apps
• A current export of your product catalog, customer list, and order history
• A list of every app or integration currently in use, including any custom-built connections
• Clarity on which features are must-haves at launch versus which can be phased in afterward
• Analytics access so historical performance data can inform redirect priorities and template decisions

Once the store is live on Shopify, many merchants also look at follow-on work like theme refinement or tighter integration between Shopify and their existing ERP or Amazon channels — but that’s typically a phase-two conversation once the core migration is stable.

Frequently Asked Questions

Will I lose my SEO rankings when migrating from BigCommerce to Shopify?

Platform migrations carry inherent SEO risk if handled poorly, primarily through broken redirects, lost metadata, or duplicate content issues. A careful migration process — including full URL mapping, 301 redirects, and preserved metadata — is designed to minimize disruption. No agency can guarantee specific rankings or timelines, since search engine behavior involves many factors outside any single migration’s control.

Can all my BigCommerce product data transfer to Shopify?

Most core data — products, variants, customers, and order history — can be migrated, though BigCommerce and Shopify structure some of this data differently (variant limits, custom fields, and metafields in particular). Part of the audit phase is identifying where data structures don’t map 1:1 and deciding how to handle those cases before migration begins.

Do I need Shopify Plus, or is standard Shopify enough?

It depends on your order volume, checkout customization needs, and integration complexity. Shopify Plus offers more flexibility around checkout customization and is often the right fit for higher-volume merchants with custom ERP or CRM requirements, while standard Shopify is sufficient for many smaller to mid-sized catalogs.

What happens to my existing apps and custom integrations during migration?

Apps tied specifically to BigCommerce don’t carry over — each one needs to be replaced with a Shopify-native equivalent or, in the case of custom integrations like ERP connections or Amazon sync, rebuilt for Shopify’s architecture. This is typically scoped during the audit phase so there are no surprises once development begins.
