If booting from ZFS, just update your boot loader. I have updated a couple of systems from 12.2-RELEASE-p3 to 13.0-RC2. One using UEFI and the other using legacy bios with no problems. for UEFI I mounted EFI Boot partition EFI update, New ZFS data set was mounted at ROOT, zpool is mirror. Updated both EFI partitions in case primary goes offline. zpool set bootfs=ssd/ROOT/13.0-RC2 ssd mount -t msdosfs /dev/ada0p1 /mnt cp ROOT/boot/loader.efi /mnt/EFI/BOOT/BOOTX64.efi umount /mnt mount -t msdosfs /dev/ada1p1 /mnt cp ROOT/boot/loader.efi /mnt/EFI/BOOT/BOOTX64.efi umount /mnt Legacy Bios, again new ZFS data set was mounted at ROOT, and zpool is mirror, updated both boot partitions zpool set bootfs=zroot/ROOT/13.0-RC2 zroot gpart bootcode -b ROOT/boot/pmbr -p ROOT/boot/gptzfsboot -i 1 ada0 gpart bootcode -b ROOT/boot/pmbr -p ROOT/boot/gptzfsboot -i 1 ada1 Everything worked as expected. -- Thanks, Dean E.

Re: Updating to 13-stable and existing ZFS pools: any gotchas?
I’ve updated two machines and had no problems, read the mailing lists and remember no problem apart from the boot loader. Updated the boot loader before upgrading the pools, found the way for EFI is different then I remembered (mount EFI partition, copy /boot/loader.efi to it) but it worked just fine.. So, while I cannot 100% guarantee it’s without problems, I would expect no hiccups. And the new bootloader is only needed if/once you upgrade your pools, I actually run my laptop for a week with quite an old loader ;) Cheers, Mathias Stefan Bethke writes: I'm planning to upgrade three production machines with existing ZFS pools to 13-stable.
