Because of certain restrictions from the platform, “Preserve customer IDs” may not work properly in some cases below.
- For X-Cart 4.3.x and lower:
Though “Preserve customer IDs” additional option is available to choose from the list, customer IDs cannot be preserved after migration from /to X-Cart (version 4.3.x and lower). If X-Cart is Source Cart, customer emails will be set instead of customer IDs.
Why? There is no such thing as “customer ID field” in X-Cart of version 4.3.x and lower. This makes preservation impossible.
- For X-Cart 4.4.x and higher:
If customer IDs on Source Cart include any other symbols except numbers, the IDs won’t be preserved on X-Cart as well (4.4.x and higher). Otherwise, customer IDs preservation will be performed correctly.
