Change the Apple ID for a game and not lose the progress made?
Short version of my question: can I change the apple id associated with a game to another one and not lose the progress made in the game thus far?
Long version: when there were only a few iGadgets in the house, all games and music were downloaded through Alpha's apple id and the credit card tied to that account. Now, we two folks have multiple iGadgets between the both of us and Beta has her own apple ID. Because we only used one apple id for so long, Beta has some games installed through Alpha's account and her own Beta account. Beta would now like to change the account the game PocketTimeSuck is associated with from Alpha's account to Beta's account without losing any of the progress made in this game which she has been playing for over a year.
Is there any way of re-installing PocketTimeSuck onto Beta's device under Beta's apple ID and maintain the progress in the game she has made after installing it under Alpha's apple id? Alpha would like to start playing PocketTimeSuck but cannot install it under her own apple id because it comes with all of Beta's progress.
(Also, if this is not the right forum, please let me know where I should post this question. Don't flame me, just tell me.)
