Subscription question.
 

Ok, lets say I bought an existing forum off a person. The forum had a recurring yearly subscription going for supporting members. Now, after changing the paypal email in the subscription backend from the original owners paypal email to mine, when the user's yearly subscription came up, would it go to my paypal account or stil go to the old owner's paypal? Would the old owner have to cancel all yearly subscriptions and have the members re up using my paypal or does changing the email to my paypal email on the vb backend before their renewal came up work?
