Tengo un zimbra en producción y funcionando.
zmcontrol status > runing ok

Preparo otra maquina con el mismo nombre pero otra ip distinta.
Con un bind dns local configurado para que la resolución de nombre sea correcta a la de este equipo.

Realizo una instalacion de zimbra en la misma versión.
Terminada la instalación paro el zimbra y mv /opt/zimbra /opt/zimbra.viejo
y coloco en su lugar una copia del zimbra en producción

pero
Code:
