You can run a 10.3 jail on an 11.0 host -- no problem. This is how eg.
poudriere works to build packages for all the different supported OS
While you can run an older jail on a newer host, you cannot do it the
other way round with a newer jail on an older host. Your order of
operations has to be upgrade the host first, and then the jails.
Upgrading jails with freebsd-update(8) can be tricky, as f-u detects the
current OS version by asking the kernel, and that gives the wrong answer
when running an older jail on a newer host. That's why there is a
'--currently-running /release/' option in more recent freebsd-update(8).
If you haven't got a recent-enough freebsd-update then there's a trick
-- so upgrading a 10.3 jail to 11.0 would looks like:
# env UNAME_r=10.3-RELEASE freebsd-update -r 11.0-RELEASE upgrade
and then do all the usuall 'freebsd-update install' steps similarly.
Other methods of upgrading jails generally work identically to how they
do when upgrading the host system.
