Upgrading FreeBSD 12.2 to 13.0
Contents
Introduction
We assume root on ZFS.
Everything on this page needs to be done as root, unless specified, so su to root.

Upgrade base system
We will do the upgrade offline, in a new BE, so first, create the BE and mount it.
bectl create 13.0-RELEASE bectl mount 13.0-RELEASE /mnt
Then run freebsd-update(8):
freebsd-update -b /mnt -d /mnt/var/db/freebsd-update -r 13.0-RELEASE upgrade freebsd-update -b /mnt -d /mnt/var/db/freebsd-update install freebsd-update -b /mnt -d /mnt/var/db/freebsd-update install freebsd-update -b /mnt -d /mnt/var/db/freebsd-update install
Yes, you really need to run it that many times.
Upgrade the bootloader
BIOS
First, determine your boot devices.
z800:aram$ zpool status zroot pool: zroot state: ONLINE scan: scrub repaired 0B in 00:01:46 with 0 errors on Mon Feb 5 17:48:15 2018 config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 gpt/zfs0 ONLINE 0 0 0 gpt/zfs1 ONLINE 0 0 0 errors: No known data errors
Look for the devices in the GEOM output.
z800:aram$ geom -t
...
da0 PART da0p3
da0p3 DEV
da0p3 LABEL gpt/zfs0
gpt/zfs0 DEV
zfs::vdev ZFS::VDEV
...
da2 PART da2p3
da2p3 DEV
da2p3 LABEL gpt/zfs1
gpt/zfs1 DEV
zfs::vdev ZFS::VDEV
...
In our case, we need to install the new bootloader on da0 and da2.
gpart bootcode -b /mnt/boot/pmbr -p /mnt/boot/gptzfsboot -i 1 da0 gpart bootcode -b /mnt/boot/pmbr -p /mnt/boot/gptzfsboot -i 1 da2
EFI
TODO.
Upgrade the packages
It is unclear why we need devfs, but we need it:
mount -t devfs devfs /mnt/dev/ pkg -c /mnt update pkg -c /mnt upgrade unmount /mnt/dev/
Activate the new BE
bectl umount 13.0-RELEASE bectl activate 13.0-RELEASE
And reboot. If it doesn't work, you can revert to another BE in the bootloader.
