On VB (3.8) we use the Paid Subscriptions system for forum donators. After we received a donation (for a year) we manually upgraded the account and set the end date accordingly. After the switch to XF I saw the donators were correctly imported, but were can I check the end dates? Didn't they get imported? How is this handled?
Also in vb donators automatically recieved an email a week prior to their subscription end date. Is that possible in XF too?
I believe that only applies to recurring subscriptions. If anything changes, they break. However, most standard non-recurring subscriptions are quite robust once purchased and can only be manually edited through the particular paysite(PayPal, Google Checkout, etc).
