How do I initially create profile ID's for an imported user base?
We are developing a new Drupal website using Commerce. It is a subscription site and we have imported existing users in from a non-Drupal site. Since there are no orders and no profile ID's setup for the billing addresses, we are not able to make it easy for users coming to the new site to renew their subscription by allowing them to use the addressbook module feature of pulling up their existing billing address.
What is the best way to initially populate/create ID's with billing addresses for the existing users?
