Transferring from old to new iPad - What Apple ID do I use? (family sharing)
Hi. I bought an iPad in 2017 and my son and I shared it for a few years. I bought it for myself originally and set it up under my own Apple ID but as he got older he used it more and more and I didn't. I would just download apps for him, buy in-app purchases for games when he wanted them. A few months ago I discovered family sharing so I created his own Apple ID and password and logged myself out the iPad and logged him in using his own Apple ID login. I could then authorise payments using my iPhone if he wanted to make in-app purchases which is much easier and what I probably should have done years ago had I known about it.
I have since bought him a brand new iPad purely for his use and was in the process of transferring everything from my old iPad to his new iPad using iTunes. At the setup stage on the new iPad it's asking me to login with an Apple ID. What Apple ID do I use? My one that that I used for years on the old iPad (and still use on my iPhone), or his new Apple ID I created for family sharing? I don't want anything of mine on his new iPad but I downloaded many of his apps under my Apple ID, will that matter?
I hope this makes sense!! Any help appreciated, thank you.
