I currently have my website setup to take payments directly via ccbill system. I am looking into rather doing payments / memberships handles by aMember, the only problem is I have about 40 recurring members from CCBill, if I use aMember, will I be able to seamlessly transfer members from ccbill to aMember. II wold obviously need to import my CCBill customers to aMember, and allow them to keep their old passwords ( if I have to reset passwords, what is the solution to this? ). I need this transition to be as seemless as possible to old members. I am only prepared to go to aMember if this is possible, I would really really love it if I could as I have heard only good things about aMember. The worst case scenario would be to delete all CCBill members, and start from fresh, but requesting them all to resubscribe may mean I lose a great deal of them.
If you can get the data from ccBill in a CSV format, then there is a "import user" function in aMember that allows you to import the user details automatically.
