Moving Game Center scores from my Apple-ID to my daughters Apple-ID
I have an iPad, and my daughter has an iPhone. Both are currently connected to my Apple-ID, so is the Game Center account she is using on these two device. Now, I am having an iPhone of my own, finally, and would like to shift my daughter off to her own Apple-ID. Most seems to be manageable, except for her Game Centers scores. Does anyone have a recipe for how to move the scores over to her Game Center account (planned to be = her Apple-ID)?
