Patch Updates

freebsd-update -b /usr/local/jails/myjail/filesystem install

Minor/Major Updates

NOTE:

jails run the host's kernel, so uname -a won't show the release installed to the jail.
You might be able to use freebsd-version, but I haven't tested it.

first update the host

freebsd-update upgrade \
  --currently-running 12.0-RELEASE \
  -r 13.0-RELEASE

# 1st run
freebsd-update install
sudo reboot

# 2nd run
freebsd-update install
sudo pkg upgrade

next update each jail

freebsd-update \
  -b /usr/local/jails/${JAIL}/filesystem \
  --currently-running 12.0-RELEASE \
  -r 12.1-RELEASE \
  upgrade

freebsd-update \
  -b /usr/local/jails/${JAIL}/filesystem install

service jail restart ${JAIL}

freebsd-update \
  -b /usr/local/jails/${JAIL} \
  install

pkg -j ${JAIl} upgrade
