I've got a four server setup of Zimbra OSS 3.1.1 running on G5 Xserves and I'm looking to add an additional mailbox server (or perhaps 2) to decrease load on the single mailbox instance. I've got about 2000 users on the mailbox server already setup, and about 1000 users still to add.

Is there a way to move user accounts from the existing mailbox server to a new server? I'm not worried about transferring messages, just wondering if I need to delete users from one server and re-zmprov them into the new server or if the accounts can be moved.

Thanks in advance for the help
