I have reinstalled my macbook pro and now when connecting to itunes, i get a message: ipad can be synced to only one itunes library, do you want to erase your ipad and sync it with this itunes library ? I definitely do not want that. How to copy the whole ipad content to the new itunes library to start using this itunes as a new syncing medium ? I did right click on the devices - my ipad and selected back up, it did something, yet I get the same message again and the content of my ipad is obviously not in itunes. Seems like a strangely stuck process. But I hope we are not supposed to stick to one itunes library forever ?
