I have a zimbra (open source) 4.0.2 on a FC5 box (old machine).
Just purchased a new beef server, and had RHEL 4 on it.
What's the best way to "move" the zimbra from old machine to the new server?

I am also thinking of upgrading to the latest 4.5.2 (open source). Can I just install the 4.5.2 on the new server, and somehow dump all the data (mysql, ldap, data files) and import to the new server?
