    Good morning -

    My son is using an old iPad that can't be upgraded beyond 9.3.5.

    My wife just moved to a newer iPad, so I want to transfer his device over to her old one. However, I'd like to do a restore from his encrypted backup so everything carries over as it was--which means both devices need to be on the same iOS version.

    So, I've been trying to downgrade the iPad Air to 9.3.5, but it is not working. I am getting a "Declined to authorize this image on this device for this user."

    Any advice on how I can get this to work so I can do the restore?

    Thanks.

    You should be able to restore an older backup onto a newer version of the OS. You cannot do the opposite, however. If you were trying to restore a backup made from iOS 10.x to 9.3.5, it would give an error message that the restore cannot proceed.

    You haven't said if you have tried this yet or not, but I would erase all settings from the iPad Air (settings / general / reset / Erase all contents and settings) and the go through the setup, and choose to restore from the iTunes backup when it comes up in the set up procedure.

    Hmmm, I did not think it would restore a backup from an older version. Although, perhaps in the past when I ran into that it was attempting to restore a backup from a newer iOS version. That would certainly make life easier; I'll give it a shot. Thanks.

    If the backup you’re trying to restore is from a device with a newer iOS version to a device with an older iOS version, the attempt will fail. For example. You cannot restore a backup made with iOS 10 to a device running iOS 9. You can, however, restore a backup made with iOS 9 to a device running iOS 10 which makes sense because if you want to buy a newer device running the newest iOS version, you want to easily be able to move your current data over to it.

    Well that makes life much easier, thanks. I've had the issue before with a new device that apparently wasn't on the latest version that wouldn't take the backup. I took that to mean that the backup and device needed to be on the same version. Appreciate the helpful replies.
