I have a few questions regarding Unity upgrade which I think Cisco documentation is not completely clear about.
We are running Unity UM 4.2(1) on windows 2000 with off-box exchange 2003. We would like to upgrade to unity 5.x, with a brand new MCS7845 server.
After reading Cisco upgrade doc, I think the general procedures would be:
1-backup existing Unity with DIRT.
2-install same version of unity on the new hardware and restore from DIRT.
3-in place upgrade of the new 7845 to Unity5.x.
The question I have is, at what point do I connect my new 7845 server to my Windows domain? By installing the new server with windows 2003 and joining the the windows domain with the same name, how do I handle the unity server with same name but different SID?
Can someone please explain this in more details?
Many thanks for your help!
