All, I posted this last week in another forum, but I have not had any reply. Sorry for the duplicate, but in real need of help.
All, my customer wants me to upgrade their unity 4.0(3) server to unity 4.0(5) so that they can migrate to win 2003. Im not sure really even how to do the upgrade. The upgrade guide is very confusing to me, so are there any pointers from you guys out there that might help me out? This has unified messaging also as part of it with Exchange. Id appreciate the help and guidance. Thanks.
Since you are using Exchange 2000, your options are pretty limited. If you want to use Windows Server 2003, Cisco requires that the partner server be an Exchange 2003 server if you are using Windows Server 2003 for the OS.
At this point, I would recommend that you upgrade from 4.03 to 4.2. The upgrade is very straight forward and consists of the following steps:
Use the following guide when performing the upgrade:
You do the install over the top of the existing Unity installation. Basically, you reinstall the application, but you don't uninstall Unity like you would Microsoft Office for example. DiRT is the only TAC supported tool for backing up Unity. I highly recommend it.
Nothing should change in CallManager or on Exchange. I would make sure that Exchange 2003 is patched to Service Pack 2 and make sure that the Exchange System Tools installed on the Unity Server are also Service Pack 2.
With regards to your second question, you can only restore a Unity backup to the same version.
