Let me clarify my question. I am going to install Exchange 2003 on a Windows 2003 cluster. Logistically, I'll have to delay my implementation of Exchange 2003 a few weeks if I need to switch to a Windows 2003 native mode domain and/or forest prior to implementation. I am upgrading my FSMO servers to Windows 2003 this weekend and my AD will be in Windows 2000 native mode. > > Here are my questions: > > 1. Assuming that I have a mixture of Windows 2003 and Windows 2000 SP3 domain controller, is there any reason that I should wait until all domain controllers are upgraded to Windows 2003 and the domain is converted to Windows 2003 native mode before I begin my Exchange 2003 implementation. Obviously, there are a couple optimizations that I'll receive once I can convert to Windows 2003 native mode. At this point you could move to Windows 2000 Native mode, but can't go to 2003 Native mode until all DC's are at 2003. However, this should not have any effect on when you choose to introduce Exchagne 2003 (you just won't get some of the "extras"). 322692 HOW TO: Raise Domain and Forest Functional Levels in Windows Server 2003 http://support.microsoft.com/?id=322692 > 2. If I start my Exchange 2003 implementation (i.e. run ForestPrep, DomainPrep, Upgrade the ADC/SRS, Run Setup on a server) before I complete upgrading the remaining servers to Windows 2003 and convert to Windows 2003 native mode, are there any complications that may arise due to being in Windows 2000 native mode? None > > 3. Assuming that I complete my Exchange 2003 implementation (using Windows 2003 servers) while my Active Directory is in Windows 2000 Native Mode (running Windows 2003 on the FSMO servers), are there any features that will not work correctly or complications after promoting my domain to Windows 2003 native mode (once the rest of my domain controllers have been upgrade)? No features that will not work correctly, but again, you wouldn't have the "extras" that are available in Windows 2003 native mode. You can, at this point, continue on with your migration plans and not push to go Native until you are ready to do so. > > Thanks for you help, > Chris > > ----- Steve Antonio [MSFT] wrote: ----- > > This article provides some details: 822178 Overview of Dependencies and > Requirements for Exchange Server 2003 > http://support.microsoft.com/?id=822178 > > In addition, the Exchange 2003 Technical Library will have some info as well > (www.microsoft.com/exchange/library) > > Some of this includes query-based distribution groups, single-value > replication, full support for InetOrgPerson. > > Hope this helps. > > -- > Cheers, > > Steve Antonio > Microsoft Exchange Support > > This posting is provided "AS IS" with no warranties, and confers no rights. > > Note: Please do not reply to this e-mail address.
