My family has shared an iPad for many years using my mom's Apple ID. Recently my mom got an iPhone for herself. She needs to now keep her Apple ID for personal use. We would like to create a new Apple ID for the iPad now and continue to use the iPad shared among the entire family. The concern is over losing app progress when the switch is made.
How will app ownership be affected by this change? Will apps disappear because the original purchaser is no longer logged in on the iPad?
Will saved progress disappear when a new Apple ID takes over the iPad? Or does progress remain saved on the iPad hard drive?
What will happen to achievements in Gamecenter? Will they update to where they were when the new Apple ID launches a game that has already been there for years?
