Migrating from BigCommerce to Shopify

The Store Importer app can migrate your product, order, and customer data from BigCommerce to Shopify. You need to export your data from BigCommerce before you can import it to Shopify.

Step 1: Export your store data from BigCommerce

The first step in store migration is to export the product, customer, and order data from BigCommerce. When your export is complete, your computer downloads CSV files containing your BigCommerce data, which you can use to import that data into Shopify.

Export your product data from BigCommerce

When exporting your products from your BigCommerce store, be sure to export additional product and variant information as well to export complete product data.

Steps:

  1. From your BigCommerce dashboard, go to Products > Export.
  2. Under Export Template and File Format Options, select Default and then click Continue.
  3. In the Products dialog box that appears, click Export my Products to a CSV file and then click Close. A CSV file containing your product data is saved to your computer.
  4. Under Export Template and File Format Options, select Bulk Edit and then click Continue.
  5. Click Export my Products to a CSV file and then click Close. A second CSV file containing additional product details and variant data is saved to your computer.

Export your order data from BigCommerce

  1. From your BigCommerce dashboard, go to Orders > Export.
  2. Under Export Template and File Format Options, select Default and then click Continue.
  3. In the Orders dialog box that appears, click Export my Orders to a CSV file and then click Close. A CSV file containing your order data is saved to your computer.

Export your customer data from BigCommerce

  1. From your BigCommerce dashboard, go to Customers > Export.
  2. Under Export Template and File Format Options, select Default and then click Continue.
  3. In the Customers Export dialog box that appears, click Export my customers to a CSV file and then click Close. A CSV file containing your customer data is saved to your computer.

Step 2: Import your store data into Shopify

After you export your products, orders, and customers from BigCommerce into CSV files, you can import these files into Shopify.

Steps:

  1. From your Shopify admin, click Apps > Import store.

  2. On the Import your data into Shopify page, select BigCommerce from the drop-down menu.

  3. Under Upload files, click Add file and select your exported files. You can select any number of CSV files. When importing products, you need to add the exported files for both the Default and Bulk Edit templates for the data to import properly.

  4. Click Continue import > Import.

Step 3: Review and update your imported data

If your data import was successful, then your product, order, and customer data is now available in your Shopify admin. If some of your products or customers didn't import successfully, then you can add them manually. For more information, refer to add a product or add a customer.

The following sections describe some of the behaviors that you might see while importing your BigCommerce data into Shopify:

Import was successful with changes

When your import is finished, the import summary page shows you the details of your import. Review the messages in the review section of the import summary for any errors. You can edit your imported information manually by clicking View items next to these messages.

Historical orders

Orders that were imported from your previous platform are migrated to your Shopify store only for historical purposes. These orders are automatically set to the Archived status. While you can technically unarchive them, you'll not be able to perform any functionality normally reserved for orders created in a Shopify store.

Some products, customers, or orders failed to import

If some of your products or customers didn't import, then you can add the products manually or add a customer.

Any customers with the same email address or phone number aren't included in an import. If two or more customers share an email address or phone number, then only the most recently created customer entry is imported.

Products imported successfully but aren't published

If any of your products in BigCommerce had their product visibility set to hidden when you exported your data, then those products are imported into Shopify as hidden, as well. If you don't want a product to be hidden, then make it available for the sales channels of your choice.

Product variants failed to import

If your product has variants and one of the variants is missing an option, then the product isn't imported. You need to add this product to Shopify manually. For example, suppose that you sell T-shirts that have different options for size and color. If one of your variants includes information about its size but not its color, then your product isn't imported.

Imported products no longer have their dimensions

If your customers need the dimensions of your product, then add the dimensions directly to the product description.

Tags applied to imported records

The Import Store app applies tags to imported records. Tags make it easier to find the things you've imported, review them for errors, or make adjustments.

Tags that are automatically applied to each imported record are in the following format: import_<date>_<import_id>. Tag formats for any import errors, such as a missing image or duplicated variant, vary based on the platform that you are importing from.

You can keep these tags on your imported records, but this might create problems if you use tags as a method of organization for your store. For example, these tags could be visible to your customers on your online store. To avoid this, you can remove them once you've checked your imported records for errors.

Import data on top of an existing import

If you think you missed something in your previous import, then you can import your store data again on top of your current import by clicking Start new import.

  • If your Shopify store or previous import already contains customers, then they are updated. The customers are first matched by email address, and then telephone number if no email address match is found. If a match is found, then the existing record is updated as follows:

    • Tax exempt and marketing subscription statuses are overwritten.
    • Tags, addresses, and notes from the import are added.
    • If the first name, last name, or telephone number fields are empty in the existing record and included in the imported customer record, then they are added.
  • If an import contains products that are already on your Shopify store, then the matching products in the import are skipped and not imported. A list of the skipped products is shown in the Import summary after the import is complete.

Delete a store data import

If you’re unsatisfied with a data import, then you can delete it. For example, if your data import contains many failed items, then it might be helpful to remove that import and try again. You can delete only your latest import. Wait for the data to delete completely before you start another import.

Steps

  1. On the Import complete page, click Delete import.

  2. On the Delete import dialog, click Delete import.

After all your imported files are deleted, click Start new import to start another import.

Considerations for customer passwords

Because passwords are encrypted, you can't migrate customer passwords from another platform to Shopify. As a result, only customer records are migrated to Shopify instead of customer accounts.
