A readers digest version of transferring a jail from one host to another.

[Kaya Saman]

Just to chime in here quickly as I have had to do this too, however, not 
using ezjail - forgive me if this has already been mentioned as I've 
just caught the tail of the thread and of course don't want to hijack 
anyone elses input...


For me I usually stop jail:

/etc/rc.d/jail stop <jail_name>

rsync -"flags" path/to/jail "rsync:"/new/path/to/jail


eg. rsync -avvc --progress --remove-source-files /jl/myjail 
rsync://10.0.0.1:/jl/myjail


then start the new jail on host 10.0.0.1: /etc/rc.d/jail start myjail


this is an alternate as an FYI :-)


Regards,


Kaya
