Has anyone experienced not being able to transfer iBooks from an old iPad 2 to a newer iPad Air 2? I've been on the phone with Apple Tech Support for three days off and on only to resolve that it's not possible to do. iTunes apparently doesn't backup iBooks. That is a serious issue since I have over 800 PDFs saved from over 2 1/2yrs of research. I need help with a workaround for iTunes on a windows pc.
