I am currently using Plenigo as my subscription management software to handle payments and maintain a paywall on my Drupal 7.7 instance. I have accumulated over 1500 customers and am now considering exploring alternative tools for this purpose.

I am looking for recommendations on reliable alternatives to Plenigo that are compatible with Drupal 7.7. Additionally, I would appreciate guidance on how to effectively migrate my existing customer data from Plenigo to a new tool. Specifically, I need to know the best practices for exporting customer data from Plenigo and importing it into the new subscription management system.

Any insights, experiences, or step-by-step instructions on the migration process would be extremely helpful.

Thank you in advance for your assistance!
