I would expect the password files not to be directly compatible, and probably a few other things like sshd_config would be out of date too. Either way I think you should have a crack and report back just how bad the breakage is :-). 10 years ago would be 9.x approx, a great deal has changed, hopefully for the better. The zfs pool layout is different now too, IIRC, so boot environments might not work OOTB. I would be concerned about being easily able to revert, for example. You could test the waters by installing 14.1-RELEASE onto a USB stick or external drive, and seeing if you can use that boot loader, to boot the older version or not. good luck! A+ Dave
