Greetings: Since I can't locate a description of what I'm am trying to do in any of the multiple manuals I'd thought I'd finish here:
Unity 4.2.1 VM only Exchange 2K on one server. Since this server can't handle the workload of the 1100 subscribers, have installed two new servers.
One server replacing Unity called Unity4, and one for the replacement exchange called Unity-Exch which is configured as Exchange 2003.
Programmed the AD Domain Controller on the new Unity-Exch server.
Installed Unity on the new Unity4 server.
Spent more than 4hrs on line with TAC to get the SA web page to work.
Now Unity4 is working, with the messaage store pointed to Unity-Exch. Problem is all the mailbox settings in Unity4 still list Unity as the exchange store and not Unity-Exch, AND all the messages apparently are still being routed to the original Unity server.
If I add a new mailbox it is built on the Unity-Exch server.
Having read chapter 13 of the Unity Upgrade manual, and not being able to make heads or tails from it, what is the procedure to move all the mailboxes from Unity (exchange 2000) over to Unity-Exch (2003) AND get all of the mailbox settings in Unity4 to reflect the new exchange location?
