I have a zimbra in production and running.
zmcontrol status> runing ok

Prepare another machine with the same name but a different ip.
To maintain the directory / opt / zimbra sync with rsync and have a backup.
With a local dns bind set to the name resolution is correct for this equipment.

Perform to install zimbra on the same version.
After installation and I stop zimbra mv / opt / zimbra / opt / zimbra.viejo
and put in place a production copy of zimbra
