And instead of using the base W2k3 schema, it doesn’t hurt you to use the W2k3 R2 extensions.   After extending the schema appropriately, it doesn’t really matter if you first take care of your Exchange Servers or the DCs.  Just need to make sure that you upgrade the Exchange app itself to 2003, prior to upgrading the WinOS of the cluster to W2k3.   /Guido   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bahta, Nathaniel V CTR USAF NASIC/SCNA Sent: Monday, July 31, 2006 3:37 PM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] W2K3 Upgrade Domain Controller or Exchange Servers?   All,   We are rounding home base in our upgrade path to 2K3 and have our Exchange Server Cluster running W2K and EXCH2K and our Domain Controllers to upgrade lastly.  Which of them would you think would be the best to upgrade first?  We thought to upgrade the DC's first because it takes care of the extension of the schema and all which has to be done prior to EXCH2K3 anyhow.  I cant think of a reason to not upgrade the Domain Controllers before the Exchange Server.  Can anyone else?     Thanks   Nate
