software too old to restore
My new iPhone 8 has the latest iOS version 11.2.5 and my old 6 had 11.2.2 but I received the error: The backup cannot be restored because the software is too old. I updated the 6 to the same version, took another backup, same error. I found steps on how to resolve this by apple-set up as new, update software, wipe, retry restore but I don’t think I should be receiving the error to begin with when the new phone had the latest version.
iPhone 8, iOS 11.2.5
