Hi, there is "How to upgrade Windows 2000 domain controllers to Windows Server 2003" (kb325379) and the information that the Exchange 2000 schema defines three inetOrgPerson attributes with non-Request for Comment (RFC)-compliant. I'm looking for following migrationpath. - Upgrading Exchange 2000 to Exchange 2003 in an active directory with Windows 2000 domain controllers. Questions: - By upgrading AD and Exchange 2000 to 2003 what should done first? a. adprep and upgrading dc's to 2003 and then Exchange 2003 forestprep? b. First do Exchange 2003 forestprep and then upgrading dc's to 2003? Thanks! Sohejl
Hi, You can perform the upgrade in any order but if you run the exchange setup /forestprep first there is no problems with mangled attributes that you could get if you run adprep first.
