I need to migrate a Windows Exchange 5.5 server to a new Windows 2003 Server computer running Windows Exchange 2003 server. Here is my current setup:
Exchange 5.5 server is currently running on a Windows 2000 Server also a Domain Controller. The Windows 2000 Server DC is also running Active Directory, DNS, WINS and DHCP. I want to migrate Exchange 5.5 to a new separate computer running Exchange 2003 on a Windows 2003 server OS.
I tried doing the migration in a LAB environment with only 2 machines having the same network configuration. I am unable to move mailboxes to the new Exchange 2003 server.
I’ve read all the scenarios about migrating 5.5 to 2003, but not really close to my configuration, that is running 5.5 in a Domain Controller running almost everything in it.
If someone can help me or point me to the right direction.
