iOS 9 iCloud Restore

Hello,

Shattered my 5S which was running iOS 9 Public Beta.

So, when I bought the 6 Plus, it needed upgraded to latest iOS 8.4 or whatever. That's been done; did an iCloud restore from my latest iOS 8 backup, no issues.

However, I've got more RECENT backups -- from when I was on iOS 9.

My question is, once I upgrade again to iOS 9 on my 6+, will I then be able to restore an IOS 9 based iCloud backup? I would assume so.

Thanks.
