Upgrade to UM

Unanswered Question

We're currently planning to upgrade a 3.13c VM system to UM. The current system uses a separate W2000 Domain Controller but Exchange 2000 is installed on the VM box. We just switched our email from Lotus to Exchange 2000 and now we want UM, but we don't want to lose old VM messages. As part of this process, we would like to home all users "off box" on the new Exchange server. I'm wondering what the best approach would be. Has anyone successfully completed an upgrade/migration such as this and if so, what was the process?<br><br>Thanks,<br><br>

I don't quite understand why I need to reinstall Unity. If the new Exchange server is in the same site, can't I just move the mailboxes to the new Exchange server and then run the config utility and point Unity to the new server?

It sounds like I'd be losing saved messages if I took the database export/reinstall approach. Is that true?

Oh OK. I kinda miss read your first post and thought you have 2 different forests. You don’t need to run Configuration Setup again. You can move to user mailboxes the Unity_server name mailbox to the new Exchange server. Unity will automatically find the moved user mailboxes but you need to make a few registry changes to point Unity to the other Exchange server.

You need to change:

HKEY_LOCAL_MACHINE\SOFTWARE\Active Voice\Doh\1.0\Mail Server Name
HKEY_LOCAL_MACHINE\SOFTWARE \Active Voice\MalEx\1.0\ServerName

After the changes and all is working you can uninstall Exchange 2000 from the Unity server.
