I've got an old nas that's running 9.10 that I've not been motivated to touch for a long while... but I think it's time to upgrade to something actually supported and developed on, so 12.0-U2, I guess. The question is: can I just upgrade straight from 9.10 to 12.0-U2 without any interim stages or is that madness? I've read a few posts (e.g.) that detail things to be aware of between particular major releases but is jumping multiple major releases a thing?
I do have an encrypted raid-z pool of 3*8TB HDD that i'd rather not decrypt or have to restore from the backup because it'd take ages. The system dataset and the jails are on a seperate (unencrypted) 120GB SSD though, and I think the actual boot is off a USB key connected directly to the mainboard, (might even be two of them, I forget now and the inside of the box is a jumble).
Worst case, I'm willing to put up with recreating jails and setting stuff up again as long as the encrypted pool is going to be okay.
