Try copying the jail first as follows to retain permissions:

stop the jail
mkdir /usr/jail/newjail
cd /usr/jail/origjail
tar -cpf - . | tar -C /usr/jails/newjail -xpf -
(don't worry about sockets not copying)

If you want to copy the jail, change hostname, delete ssh public keys
and change any other info pertinent to the jail. I just grep the
hostname and ip in /etc and /usr/local/etc. Test the jail. It should
work fine.

If you want to remove the original jail,

chflags -R noschg origjail
rm -rf /usr/jail/origjail

Ezjail really is very good too. You can convert your existing jails
into the ezjail framework easily.
