I have an iPad I am getting rid of, and I will be getting a new iPad down the road to replace it. Once I get the new iPad, I would like to restore the iTunes backup that came from this iPad. I have backed up this iPad via iTunes encrypted, so I maintain passwords etc. It was backed up when iOS was/is on iOS 12.3.1. If, once I get a new iPad, iOS is on version 12.5 for example, will it be able to successfully restore the backup made with iOS 12.3.1? If not, how do I preserve my iTunes backup data when I need to restore it down the road with a different, newer iOS in place? Am I forced to use its iCloud backup (losing passwords etc. as that is not encrypted)? Thanks!
