by coincidence i've finished moving a jail-environment from 1 disc to
a bigger disc and then to another machine today

unfortunately i "had" to rebuild world because the clock was wrong and
got a "touch: file not found" which turned out to be a FAQ after i
already restarted with "time make buildworld" etc. but of course
normally that shouldn't happen

in your case you already have another disc ready, and if e.g. your
jails are in /usr/jails/ then
you would replicate the relevant /etc/rc.conf content (without ezjail that is)

not sure where ezjail saves it's config-files, but that's probably
easy to replicate too
