I just purchased two new servers running Windows Server 2003. I would like to promote the new servers to domain controllers, move the FSMO, PDC and Masters roles over to the newly promoted DC, and then demote the two Windows 2000 Server DCs.
Is it okay to run forestprep and domainprep even if they were run before setting up Exchange Server? Is it okay to run it a second time? What other things do I need to do to upgrade Active Directory to Windows Server 2003?
