Simple question really and I'm sure there's already a thread/discussion on it. Wondering if anybody has some experience with this. Anyone else in my position: I'm running iOS 9.1 Beta on my 6 Plus at the moment and my 6s Plus arrives on Friday. At the moment I back up to iCloud and that works completely fine. A few weeks ago I restored my iPhone that was running iOS 9 beta with a backup that was made with the same device/OS version (i.e, wiped the phone and restored from a backup right after). When the 6s arrives, will I be able to set it up from my 6 Plus's backup despite the 6 Plus running a later beta version of iOS? 6 Plus: 9.1 beta 6s Plus: Final build of 9.0 I assume. Does anyone have experience with this sort of thing? Has anyone ever restored a phone running release software from a beta software backup? Last resort would be to follow these instructions but that will certainly be a pain to do. EDIT: Found other threads about this so I'll ready up on those. Another possibility would be to upgrade the 6s to the 9.1 beta as soon as I get it but due to battery life concerns I'd much rather stick with 9.0 stable.
