Thanks. It's a ZFS on root system, raidz2, GENERIC kernel, Xeon E3-1220. I upgrade with the standard source rebuild procedure. > The bootcode is not touched by upgrading FreeBSD.

Sure, I update the bootcode after installworld to keep things in sync. The question is is there not eg. a chance of downgrading features by going to an earlier dated 13.0-RELEASE version and not being able to boot. Yes before running zpool upgrade. > If you want the pools to not be upgraded "accidentally" you can do something > like "zpool set compatibility=freebsd-12.4 <pool-name>". > Different compatibility versions can be found here: > # ls -l /usr/share/zfs/compatibility.d/ Thanks, I have no /usr/share/zfs directory though? To rephrase: is it safer to go from 12.4-STABLE -> 13.3-STABLE, or 12.4-STABLE -> 13.0-RELEASE -> 13.3-STABLE
