Is it possible for me to migrate from an existing Membership system?

Yes, as long as you can export your data (either via an export script or the database), you can use our MemberPress Importer add-on to easily import Users, Products, Coupons, Rules, and Transactions. You can even import active, automated recurring Subscriptions with PayPal Express Checkout, Authorize.net ARB, or Stripe. You can read more about it in our User Manual.
