Planning our upgrade..
Windows 2000 SP3
This is just an VM machine, NO unified applications..
Target Machine (totally sepereate):
Windwos 2003 R2
Exchange 2003 (possibly 2007)
From what I've read in Cisco doc's and going back through the forum here this doesn't sound to difficult (I don't think).
Here's my plan:
1. On the new to-be 5.0 server, Install Unity 4.x and make this server as identical as possible to the current prodcution machine.
2. DIRT the current machine and restore to the to-be 5.0 machine (currently 4.0(2))
3. Once DIRT Restore is done - upgrade to 5.0
a. Get 5.0 License File
b. Upgrade Exchange
c. Upgrade Unity
Simply as that?
Or, would I better off upgrading our current machine to the latest - doing an In Place Upgrade - and then moving to the new server?
I'll keep rearching, but if anyone has a good doc or an upgrade check list they used, that'd be great!
You cannot inplace upgrade your Unity server from Windows 2000 to Windows 2003. This is not supported. In addition, Unity 4.0(4) is the minimum for running with Windows 2003. I could be wrong, but I don't think Exchange 2007 is supported for onbox Exchange, and in addition you would need to be running Windows 2003 64bit version to support Exchange 2007. On the new server, I would go Windows 2003 SP2, since R2 = SP1. Check out this 5.x doc - http://www.cisco.com/en/US/customer/docs/voice_ip_comm/unity/5x/upgrade/guide/ex/5xcuruge020.html
Therefore, I would:
1. Upgrade your current Unity server to 4.0(4)
2. Install new server with Windows 2003 and Exchange 2003. Install Unity 4.0(4) on new server in demo mode to test.
3. DiRT backup current production server
4. DiRT restore to new server
5. Upgrade Unity on new server to 5.x
You mentioned voicemail only, but no voice cards I assume.
