I have to move my Zimbra (in VMware) to a new datacenter. I chose to make a clone, relocate the clone to the new location.
The cloned Zimbra appears to be working fine from initial test, though not all domains are switched over yet to it, only a single "test" domain.

Is there a method to transfer over the accounts from the old one, which is still in use, to the cloned one, which has all the same accounts, just out of date.
It seems that this might require less downtime than stopping the original server and cloning it again and physically moving it over. I have considered just transferring online, but we've limited bandwidth.

Or is there some alternative methods for such a move?

Thanks,
