Migrating an online store requires careful planning to protect product data, customer records, and SEO rankings. BigCommerce offers flexible tools for managing products, payments, and integrations. A successful BigCommerce store migration involves preparing data, configuring the new store, testing essential features, and preserving search visibility.

Why Should You Migrate Your Online Store to BigCommerce?

An existing eCommerce platform may no longer meet your store's technical or operational needs. Limited integrations, high maintenance costs, and restricted features can make store management difficult.

BigCommerce provides hosted infrastructure, built-in commerce features, and integration options for different selling models. Before starting an eCommerce platform migration, review your store's requirements, catalogue size, payment methods, and connected systems.

What Should You Prepare Before Migration?

Preparation helps prevent data loss and unexpected delays. Audit your existing store, back up important records, and identify the features that must remain available after migration.

Document product data, customer accounts, order history, website URLs, and third-party integrations. Set a timeline and budget, and decide how to handle new orders during the transition.

What Are the Key Steps in a Successful BigCommerce Migration?

A structured process helps keep migration tasks organised and reduces the risk of technical errors. Complete each stage carefully before moving to the next.

Step 1: Audit Your Existing Store

Review products, categories, prices, images, customer records, and order history. Identify essential applications, custom features, and integrations that need to be transferred or rebuilt.

Step 2: Clean and Prepare Data

Remove duplicate records, correct missing information, and standardise product SKUs. Map the existing data fields to BigCommerce fields and test a small import before transferring the complete catalogue.

Step 3: Set Up Your BigCommerce Store

Configure currency, taxes, shipping, payments, and customer account settings. Select a suitable theme and check navigation, product pages, and mobile usability before importing the full catalogue.

Step 4: Migrate Products, Customers, and Orders

Transfer the required data using supported import tools, migration applications, or APIs. Validate product variants, inventory levels, customer records, and order details to confirm that the information has transferred accurately.

Step 5: Reconnect Integrations

Configure payment gateways, shipping tools, analytics, and marketing applications. Test connections with ERP, CRM, and inventory systems to ensure that orders and product updates synchronise correctly.

For technical configuration and shopfront improvements, BigCommerce development services can support the migration requirements.

Step 6: Protect SEO Rankings

Create a mapping of existing URLs to their new destinations. Set up permanent redirects for changed URLs, update internal links, and review metadata, canonical tags, and the XML sitemap.

Step 7: Test Before Launch

Test checkout, payment processing, shipping calculations, discounts, customer accounts, and order notifications. Check mobile responsiveness, page speed, and integration workflows. Resolve critical errors before launching the new store.

Step 8: Launch and Monitor Performance

Connect the domain, verify SSL, and perform a final data synchronisation if the existing store is still receiving orders. After launch, monitor checkout errors, inventory updates, organic traffic, and indexing issues.

What Are the Common BigCommerce Migration Challenges?

Even a carefully planned migration can involve technical difficulties. Understanding the likely challenges helps you prepare solutions before they affect store operations.

Data inconsistencies: Different platforms may organise product variants, customer information, and order records differently. Field mapping and sample imports help reduce errors.

SEO fluctuations: URL changes and missing metadata can affect organic visibility. Redirects, updated internal links, and post-launch monitoring help protect important pages.

Integration compatibility: Existing applications may require replacement or redevelopment. Check API availability and integration requirements before migration begins.

Unexpected costs: Custom functionality, data cleanup, and testing can increase the project budget. Define the scope and identify technical dependencies early.
