Authorize.Net CIM: How do I migrate from another CIM extension to the ParadoxLabs version?

In order to convert from another Magento 2 Authorize.Net CIM solution to our own Magento 2 extension and carry the cards across, you'll either need to:

Migrate the stored card data directly into our database table paradoxlabs_stored_card (including card details, customer, billing address, expiration, etc.)

OR

Set each customer's "Authorize.Net CIM Profile ID" authnetcim_profile_id attribute to their CIM profile ID from your original solution, and set their "authnetcim_profile_version" attribute value to 100. That will cause our extension to import cards for the customer from CIM the next time their cards are accessed. If their authnetcim_profile_version is already set to 200, which will happen if you or they view their cards or checkout, that import won't occur. By default neither attribute is shown on any forms, so you would need to set these values in the database or with a customer export and import.

If you are migrating between Magento versions (Magento 1 to 2), please see our article on that migration.
