I know there I recently ran into the problem of not being able to access 5.x file systems and 5.x backups from a 4.x system. (5.2+ and 4.7 & 4.8, IIRC.) (I got a new amd64 computer that wouldn't boot 5.x from the old hard drives because I no longer had a GENERIC or other compatible kernel and I had no Internet access or 5.x CDROM. I could run 4.x, but it couldn't mount 5.x partitions or even "restore" 5.x dump backups. Had to go back to an old 4.x backup until I got back on the Internet and got 5.x going.)
