Shopify to BigCommerce Migration Services

Migrating from Shopify to BigCommerce is never an easy task, especially when you’re running a large and complex store. This process involves several steps that require a meticulous approach to ensure no data loss or site crash during the migration. Now, if you’re ready to transfer from Shopify to BigCommerce, here are two main methods you could follow to execute a successful migration.

Method 1. Migrate from Shopify to BigCommerce with LitExtension

Step 1. Technical consultation

At the early stage, all you have to do is contact us and share your requirements. Our team will analyze how the data of your Shopify store is organized and review store-specific configurations that might influence the migration. During these discussions, any special conditions, limitations, or potential risks will be identified and communicated early, so that there is complete transparency before we move forward. Once both sides agree upon all technical details and the migration scope, we will formalize the terms in a Service Level Agreement (SLA). The moment you review and approve the SLA, our Shopify to BigCommerce migration officially begins. Note: On occasions, additional work may be required for manually created records, third-party data, or other non-native add-ons. But no worries; if this applies to your case, the extra fees will be clearly communicated in advance to keep the entire process transparent and predictable for you.

Step 2. Pre-migration preparation

With the scope finalized, our team will prepare your BigCommerce store for the migration. Specifically, we will configure essential store settings and establish the necessary connections to set up the destination environment. This process helps ensure BigCommerce is fully ready to receive data from your Shopify store before any transfer takes place. At the same time, we also work on data mapping to guarantee 100% accuracy during the migration. In case your Shopify store uses custom fields or non-standard data structures, the migration rules will be tailored accordingly so that all information fits correctly once it is transferred into BigCommerce.

Step 3. Demo Shopify to BigCommerce migration

Now that the BigCommerce environment has been fully prepared, we move on to the demo migration. For this step, our experts will transfer a limited portion of your data (products, customers, and orders), so you can review how your Shopify information appears and functions within BigCommerce before the full migration takes place. Preview results aside, the demo migration also allows us to identify and resolve any technical issues early on. Only after you confirm that the demo outcome meets your expectations do we proceed to the next step. Note: For eCommerce stores with fewer than 2,000 entities, this demo migration is optional and will be skipped unless you request it.

Step 4. Full Shopify to BigCommerce migration

After the demo results are approved, we proceed with the full migration phase. At this stage, our team takes complete control of the process for you. We handle all backend configurations, manage live data synchronization, and closely monitor each step to ensure stability and accuracy throughout the migration. Most importantly, as part of the All-in-One package, all additional options available in the Automated service (e.g., 301 redirects) are included by default. That means they will be implemented automatically, with no additional costs required!

Step 5. Quality assurance after migration

Once the Shopify to BigCommerce migration is fully completed, we move on to a thorough quality assurance process. Our team systematically reviews products, customer information, orders, and metadata to confirm that all data has been transferred accurately and in full. Should any inconsistencies or discrepancies be identified during this review, they will be addressed immediately.

Step 6. Post-migration services

Even after your BigCommerce store is live, our support continues during the transition period – when your Shopify store may still be generating new data. To keep both platforms aligned, we offer a set of post-migration services designed to handle ongoing changes and ensure data consistency:

• Recent data migration allows newly created data to be transferred an unlimited number of times after the migration is completed (provided it does not exceed 5% of the original data volume).
• Remigration means you can request us to redo the migration 2 times if necessary, completely free.
• Smart update enables you to synchronize updates and changes from Shopify to BigCommerce at any time after the migration is finished.

In addition to these services, you also receive 60 days of free technical support. Together, these services ensure your BigCommerce store continues to operate smoothly as it transitions into regular day-to-day operations.

Step 7. Customer support availability

Last but not least, our commitment extends beyond the migration itself. LitExtension’s support team remains available to assist you whenever guidance is needed, with guaranteed response times. With the exception of national holidays, we will make sure you always have access to timely, reliable assistance whenever questions or issues arise.

Method 2. Manually transfer data from Shopify to BigCommerce

While using an automated tool can simplify the migration process, some store owners may prefer to carry out the Shopify to BigCommerce migration manually. This method gives you complete control over the transfer process, but please keep in mind that it requires much more time, effort, and technical skills. Each step must be performed with precision to avoid data loss or disruption to business operations. Therefore, if you are looking for a faster, more accurate, and less stressful approach, LitExtension Automated Migration Service offers a smarter solution. We handle your migration from end to end, making sure that all your essential data is transferred safely with minimal downtime. However, if you still prefer to proceed with the manual route, follow these structured steps:

Step 1. Export your data from Shopify

• From your Shopify dashboard, go to “Products” > “Export”.

• In the pop-up window, tick the “All products” and “CSV for Excel, Numbers, or other spreadsheet program” options. Then, click the “Export products” button to start the process.

• Now, access the email that is associated with your Shopify store. The download link for your exported Shopify products will be shown there.

Please repeat these steps to export your customers and orders data. Unfortunately, since Shopify doesn’t support exporting everything in a single click, you’ll need to manage each dataset individually.

Step 2. Format your data to match BigCommerce requirements

Before the actual Shopify to BigCommerce, you’ll need to configure your exported data to make it compatible with the new platform’s system. This will ensure a smooth importing process later on.

• First, download a sample BigCommerce CSV file for reference.

• Then, map the data from your Shopify CSV file to match the BigCommerce CSV file. In this step, feel free to remove any column that you don’t want to add to your new store.
• When everything is adjusted, double-check your file to prevent failed imports.

Step 3. Import your data into BigCommerce

Once you CSV files are formatted, you can begin the import from Shopify to BigCommerce.

• Go to the BigCommerce admin panel and navigate to “Products” =>  “Import”.
• After that, upload your CSV files and map the fields accordingly.
• Finally, start the import and wait for confirmation.

Step 4. Test your BigCommerce store

Now that your data is successfully imported, it’s important to check every part of your store before launching to ensure it works properly with no data loss.
