I have three 2003 DCs and will upgrade AD with new windows 2008 servers.
I will run forestprep.exe. and adprep.exe to upgrade. Since I only have a single domain, I can run this once.
My questions is that what about exchange server? Currently 2003 exchange server on windows 2003 server as member of domain. After I upgarde AD, will it work automatically? Is there any tools that allow me to examine the connections with new AD? I will have both 2003 and 2008 servers for a month and will dcpromo to remove DC from 2003 servers and retire it.
Thanks in advance
