Transferring data
Is there a way where I can switch the data of an ipad to another ipad that is in use? I have 2 that are being used but I just want to switch their data.
iPad Air, iOS 12
Yes. Create an iCloud or iTunes backup of both devices - and then restore the backup of each to the other iPad:
