We are about to upgrade our current Windows 2000 domain by adding a new Windows 2008 domain controller. The short-term plan is to leave exisiting windows 2000 DC's in place, replacing them later in the year to raise the domain level to 2008.
We have a single Exchange 2000 server at present that will be replaced sometime after the initial Windows 2008 DC install.
What needs to/should be done (extend schema?) to the Exchange server pior to/after installing our first 2008 DC?
Recommendations and details would be appreciated.
