Wix to BigCommerce Migration

How to Migrate from Wix to BigCommerce with LitExtension

Migrating from Wix to BigCommerce can be a complex process. You’ll need to handle different data structures, adjust field formats, and ensure that everything from product details to customer information moves over without errors. Even a small mistake during migration can lead to data loss, broken links, or downtime, affecting your store’s performance and your customers’ experience.

That’s why many growing businesses choose LitExtension, a trusted expert in eCommerce migration. With years of experience and thousands of successful projects, LitExtension offers a safe, accurate, and fully assisted migration process. Instead of dealing with technical headaches on your own, you can rely on a team that understands both platforms deeply and can tailor the migration to fit your exact needs.

Below is a step-by-step breakdown of how you can move from Wix to BigCommerce using LitExtension’s All-in-One Migration Service.

Step 1. Technical consultation with LitExtension experts

The first stage of your Wix to BigCommerce migration begins with a one-on-one technical consultation with our expert team. During this step, we take the time to understand your store in detail and design the most effective migration plan tailored to your business.

We start by reviewing the size, structure, and complexity of your current Wix store. This early assessment helps us identify potential challenges and define the best approach to ensure a smooth transition. We also determine exactly what needs to be transferred, such as products, customers, orders, blog posts, and other critical data, so we can estimate the time and resources required for a successful migration.

Finally, we evaluate any custom elements, including special fields, layouts, or unique workflows, that may need specific handling. This helps us build a migration strategy that keeps your data accurate, complete, and ready to perform on BigCommerce. With LitExtension’s experts guiding you from the very beginning, you can be confident your migration is carefully planned and executed by trusted professionals.

Step 2. Pre-migration customization

After the initial consultation, we move on to preparing your store for a seamless Wix to BigCommerce migration. This step focuses on setting up everything correctly to ensure your data transfers accurately and without disruption.

We start by reviewing both your current Wix store (Source Cart) and your new BigCommerce store (Target Cart) to make sure they’re fully ready. This involves gathering the required credentials, such as store URLs and access details, and confirming that your BigCommerce store is properly configured to receive incoming data.

Next comes the data mapping process, where we align your selected Wix data with BigCommerce’s data structure. During this phase, we make sure every field, from product names and SKUs to categories and customer details, matches the correct format. If your Wix store includes any custom fields or special data types, we carefully map them to BigCommerce’s system to maintain full accuracy and consistency.

By the end of this step, your stores will be fully synchronized and prepared, laying the groundwork for a reliable and efficient migration to BigCommerce.

Step 3. Run demo migration

Before we begin transferring your full data from Wix to BigCommerce, we start with a demo migration. This step gives you a clear preview of how your data will appear on BigCommerce and helps confirm that everything has been set up correctly.

During the demo, we migrate a small sample of your data, typically including products, customers, and orders, from your Wix store to your BigCommerce store. This allows us to check how your content is displayed, how well it fits into BigCommerce’s structure, and whether any adjustments are needed before the full migration.

Please note that if your total number of entities is under 2,000, the demo migration is usually skipped unless you request it. Otherwise, our system runs the demo automatically, and our team reviews the results carefully to verify accuracy and formatting.

If anything appears incorrect or needs improvement, we’ll make the necessary changes before continuing. This process ensures your migration setup is solid, reducing risk and giving you full confidence in the upcoming data transfer.

Step 4. Perform the full migration

Once you’ve approved the demo results, we move on to performing the full Wix to BigCommerce migration. This is the most important phase, where all of your selected data is transferred securely and accurately to your new BigCommerce store.

Using the custom settings finalized earlier, we carry out the migration according to a detailed plan. Every piece of data, products, categories, customers, orders, blog posts, and more, is placed in the right location and mapped correctly. We also ensure that content relationships, like product-to-category links or customer order histories, are preserved to keep your store structure consistent.

The best part is that you don’t need to put your Wix store in maintenance mode. Our migration process runs automatically in the cloud, allowing your current store to stay live and fully operational with no disruption to your business.

As soon as the full migration is complete, we’ll notify you right away so you can move on to testing your new BigCommerce store.

Step 5. Migration results testing

After the full Wix to BigCommerce migration is complete, we move on to testing the results. This step is essential to make sure that all your data has been transferred correctly and that your new BigCommerce store is working as expected.

During this phase, we carry out thorough checks to verify the accuracy and completeness of the migration. Our team reviews key elements such as products, categories, customers, and orders to confirm that everything has been imported successfully and appears in the right place. We also look for any data mismatches or formatting issues that might affect your store’s performance.

Once we’ve validated the results and ensured that everything meets your expectations, we’ll send you a project completion confirmation. This gives you peace of mind knowing that your BigCommerce store is fully functional and ready for the next steps.

Step 6. Post-migration tasks

Because your Wix store remains fully operational during the Wix to BigCommerce migration, it’s possible that new data, such as orders, customer registrations, or product updates, may be added while the migration is in progress. To help keep your BigCommerce store completely up to date, LitExtension offers a range of post-migration services designed to handle any changes made after the initial transfer.

Here’s what you’ll receive after the full migration:

• Unlimited recent data migration if your new data is less than 5% of the initial migration. This offer is available for 30 days after migration is completed.
• Free & unlimited re-migration within 30 days after the migration is completed.
• Free & unlimited smart update within 90 days after migration is completed.

Step 7. Customer support post migration

Even after your Wix to BigCommerce migration is complete, our job isn’t over. We continue to support you to make sure your new BigCommerce store runs smoothly and without any issues. If you have questions or run into any problems, our Customer Support Team is always ready to help.

You can contact us anytime within 30 days after the migration, and we’ll provide clear guidance or quickly resolve any concerns. Whether it’s a technical issue, a data-related question, or just something you’re unsure about in your new store setup, our experts are here to assist you.

Manually Export and Import Data from Wix to BigCommerce

If you prefer to handle the migration yourself, it’s possible to move your store manually from Wix to BigCommerce by exporting and importing data. However, this method can be time-consuming and requires a solid understanding of both platforms’ data structures. You’ll need to work with CSV files, perform field mapping, and troubleshoot errors along the way.

Because of these challenges, manual migration is best suited for those with technical skills or prior experience in eCommerce data management. If done correctly, it gives you more control, but without proper setup, it can also lead to data loss or a store malfunction. Below is a step-by-step breakdown to help guide you through the manual process.

Step 1. Export Wix data

To begin your manual Wix to BigCommerce migration, the first step is to export your data from Wix. Since Wix does not offer a built-in tool to export all store data types at once, you’ll need to download each dataset separately, depending on what you plan to migrate.

Step 1.1. Export Wix product data

• From your Wix Admin dashboard, select the “Product” tab.
• Select the products you want to export by ticking the boxes.
• Click “More Actions” > “Export” and wait for the process to complete.

Please note that Wix only allows export of physical items. For digital products, you may need to manually record and save the information to your device.

Step 1.2. Export Wix customer data

Wix saves its customers’ data under Contact, so keep this in mind to avoid any confusion during the exporting process.

• Go to your “Contact List” in your Admin dashboard.
• Select the customers (listed as contacts) you want to migrate to BigCommerce.
• Then, choose “More Actions” and click “Export contacts” from the drop-down list. 
• In the pop-up window, select the contact groups and export format.
• Finally, click the “Export” button and wait for the file to be downloaded.

Step 1.3. Export Wix orders

• First, navigate to the “Orders” tab in your Wix Admin dashboard.
• Then, select the orders you want to export, and click “Export”.
• Here, feel free to exclude the columns you don’t want to appear in your CSV file. 
• After that, hit the “Export” button and save your file.

Step 2. Configure data to match BigCommerce infrastructure

Before moving forward with your Wix to BigCommerce migration, you need to properly format your exported data so it aligns with BigCommerce’s structure. This step is essential to avoid errors and ensure a smooth import into your new store.

Here’s how to prepare your CSV files for BigCommerce:

• First, download a sample BigCommerce CSV file to use as a reference. This file will show you the correct column names, formats, and required fields expected by BigCommerce.

• Map your Wix CSV data to match the BigCommerce format. 
• Additionally, make sure to remove any unnecessary fields that you don’t plan to include in your new store. This will keep your file clean and make the import process easier to manage.
• Double-check your file once all fields are aligned. to prevent import failures or data mismatches when you upload the data to BigCommerce.

With everything formatted correctly, you’ll be ready to move on to the import stage with confidence.

Step 3. Import your data into BigCommerce

Once your CSV files are formatted, you can begin the import from Wix 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.
