Okay everyone here is what i have done so far with my test environment for exchange 5.5 to 2007 upgrade and windows 2000 dc to windows 2003 dc. I used acronis enterprise software and took full backups of each machine currently running the environment and then used acronis universal restore and restored the backups on to test machines in my cube area that are not on the domain. Both machines are the the exact identical to the live machines currently running. So I am confused on what to do next since I cannot add it to the domain because it gets a windows duplicate name and of course is setup for the ip as the live environment. I am wondering the best way now to make the exchange 5.5 server communicate with the windows 2000 dc for the test environment which is in my cube. Then once i get them both communicating would it be okay to go ahead and upgrade the 2000 dc to 2003 dc and then start migrating the exchange 5.5 to exchange 2003. So heres a list of the machines setup in my cube for now for testing purposes.
1 Duplicate Windows 2000 DC with Active Directory
1 Duplicate Windows 2000 exchange 5.5
1 Windows 2003 64 bit for exchange 2007
1 Windows 2003 standard for exchange 2003
2 Windows XP test machines
