I have FreeBSD set up on multiple machines, and I am looking for advice on the best way to transfer a jail from one system to another. Essentially, system A with the jails on it now, is running 7.2, and the 3 jails are also running a full 7.2. They are located in /usr/jail/cell01, /usr/jail/cell02, and /usr/jail/cell03 respectively. I have system B running 7.2 as well. I realize I'm going to have to change IP information in the main server for starting the jails, and of course configuration files within the jails themselves once they are running. What is the best way to transfer these full jail environments over to the new system? Is it as simple as tar-ing the whole jail folder structure for each jail, copying it over, and then starting it? Thanks in advance for any help, and I don't mind doing further reading either if someone can post links to such required reading.
