Jails don't absolutely need to have the same root. I'm not sure where you found 
your "JAIL_HOME" and "jails.conf" (a script?), but each jail needs a "rootdir", 
which can be a path to whatever you want. You can configure this "rootdir" in 
/etc/rc.conf. Have a look there.

Depending on how much space your actual jails are using, you may consider 
moving all your jails onto a new drive, instead of moving part of them. It is 
maybe easier to manage your system this way, although not necessary at all.

Hope this will help you,
