Migrating from BigCommerce to Shopify means moving product, customer and order data via CSV or with migration apps such as LitExtension and Matrixify, rebuilding the theme on Shopify's Liquid framework and pointing old URLs to new ones with 301 redirects. BigCommerce themes cannot be moved to Shopify as they are, and the category hierarchy is adapted to collections. The process consists of preparation, data transfer, theme, integrations, SEO, and testing and launch.
In 2026, moving to a more flexible platform has become an important decision for many e-commerce businesses. Migrating from BigCommerce to Shopify is an attractive option, especially for brands focused on scalability and ease of use. Shopify's ease of use, app ecosystem and customizable structure help many businesses make their sales processes more efficient.
In this guide, we walk through the migration to the Shopify platform step by step. We also go into detail on what to watch out for during the migration, the roadmap to follow for a successful transition and what needs to be done at the end of the process to be ready for launch.
The main goal in this process should be to transfer data without corrupting it, preserve your design identity, keep your SEO values from dropping and carry on in a way that fits the Shopify ecosystem. We cover the steps of the general migration process (choosing a Shopify plan, data transfer, SEO protection strategy, go-live checklist) separately in Migrating to Shopify: Our Complete Guide; here we focus on the theme and app migration details specific to BigCommerce.
Why Does Migrating from BigCommerce to Shopify Matter? Key Reasons for 2026
As of 2026, online customers' expectations are rising fast, and the flexibility and performance of e-commerce platforms play a decisive role in meeting them. BigCommerce is undoubtedly a strong e-commerce platform, but there is no denying that Shopify stands out with its range of apps, user-friendly interface and broader integration ecosystem.
Shopify's "no-code" approach in particular makes design, product management and marketing easier by keeping the need for technical knowledge to a minimum. In addition, with a Shopify consulting service, businesses can make full use of the platform's new features to increase their sales.
Another important reason to migrate from BigCommerce to Shopify is app integrations. BigCommerce has strong API connections, but thanks to the thousands of apps in the Shopify App Store, Shopify offers a much richer choice in areas such as automation, marketing, dropshipping and sales optimization.
How Do You Migrate from BigCommerce to Shopify?
Preparation
- Review the data in your current BigCommerce store. Gather your products, customers, orders and content.
- Set a timeline for the migration.
- Choose your Shopify plan and complete the basic configuration.
Data Transfer
- Export your product listings, customer information and order history in CSV format.
- Review the data structures Shopify expects and format your data before importing.
- Where needed, use Shopify's product CSV import feature or migration apps such as LitExtension and Matrixify. If you have a development team, pulling data via the REST API or GraphQL will also do the job.
Theme Setup and Design
- Choose a suitable theme from the Shopify Theme Store or develop a custom theme with our store setup service.
- Customize the design to fit your brand.
- Test mobile compatibility and speed optimization.
Integrations and Apps
- Configure integrations such as email marketing, CRM, payment infrastructure and social media.
- Add the apps that fit your needs from the Shopify App Store.
- Run tests to make sure the integrations work without problems.
SEO and URL Redirects
- Map the URLs from your old BigCommerce site structure to Shopify with 301 redirects.
- Check meta titles, descriptions and structured data.
- Reconnect Google Search Console and Analytics.
Testing and Launch
- Place test orders to check the payment, cart and delivery processes.
- Once you have fixed any issues, publish the site.
- Switch to live mode in the Shopify admin to activate the payment system.
Preparing Before You Move Data to Shopify: Products, Customers and Orders
All the products, variants, category structures, customer records and past orders in your BigCommerce store need to be moved to Shopify without any data loss. At this stage, consistency in images, product descriptions and metadata is especially important. When you rebuild your category structure as collections and menus in Shopify, Collection Wizard speeds things up by creating collections from your menu.
One of the most common mistakes when migrating from BigCommerce to Shopify is moving product data only at the title and price level and ignoring SEO compatibility. You need to check product descriptions, titles, tags and any custom fields and make them compatible with Shopify again.
Customer data, on the other hand, should be transferred with GDPR compliance in mind. As of 2026, Shopify has removed passwords from customer account login; customers sign in with a one-time code (OTP) sent to their email address. So you do not need to move password data from BigCommerce; on their first login, customers only verify their email.
Theme and Design Migration: Rebuilding Your BigCommerce Design on Shopify
Every e-commerce platform has its own theme structure. BigCommerce themes cannot be moved to Shopify as they are, but the code structure and core design elements can be recreated. Shopify's "Liquid"-based framework offers a very flexible structure.
The first issue to solve at this stage is preserving your brand identity. Elements such as the logo, color palette, fonts and menu structure are customized to suit the Shopify theme. Where needed, a custom theme is built or the existing theme is edited at code level. For brands that want to refresh their identity along with the migration, our e-commerce branding service covers everything from the logo and color palette to applying them in the store.
During design, special attention goes to mobile compatibility, site speed and user experience. Minimal, speed-optimized themes with high conversion rates are recommended from Shopify's own Theme Store.
Integrations and Apps: Strengthen Your Workflow with the Shopify App Store
Shopify has a strong app ecosystem that covers many of the plugins you use in your BigCommerce store or offers more advanced alternatives to them. You can add new apps in areas such as online marketplaces, social media, shipping solutions and accounting integrations.
The Shopify App Store offers a very wide range of tools, especially in areas such as automation, SEO improvement, ERP and CRM integrations and loyalty programs. The choices you make at this stage directly affect your store's efficiency.
Some custom integrations can be set up manually via the API. This work can be done quickly with a Shopify consulting service.
SEO and URL Configuration: Tips to Avoid Losing Traffic During the Migration
SEO is at the heart of the migration. Misconfigured URL redirects, missing metadata and broken links can hurt all of your rankings. That is why redirecting your old BigCommerce URLs correctly on Shopify is essential.
301 redirects preserve the authority of your old pages. You need to use the same keywords in product descriptions and page titles, keep the content structure intact and resubmit your sitemap.
Technical details such as integrating analytics tools with Shopify, Search Console notifications and robots.txt configuration are also an integral part of the process.
