Hello,

According to http://support.microsoft.com/kb/810591/en-us I can run Exchange 
2000 SP3 on Windows 2000 SP4 in a W2K3 domain and raise the domain en forest 
functional level to Windows 2003 without problem. Has anyone done this and 
can they confirm this will not cause any issue. We are now running on a W2K3 
Domain (all DC's are W2K3R2 X64 bit) but are still in Windows 2000 Native 
mode. All is well up to now and we would like to switch to domain and forest 
functional level Windows 2003.

Thx!

Hello,

Thank you for posting here!

As you say, given that Exchange 2000 is installed on a Windows 2000 member 
server that is a member of the Windows 2003 domain, then the functional 
level of the Windows 2003 domain can be raised to the Windows 2003 Forest 
Functional level.

Note the requirement for Windows 2003 Forest Functional level is that all 
Domain Controllers be Windows Server 2003 controllers.  This allows for 
Windows 2000 members servers to coexist in such a domain/forest.

Here is a document that should thoroughly detail the answer to the question 
you have raised:

"Microsoft. Exchange Server Compatibility with Microsoft Windows Server 
Operating Systems"

Sorry about the crosspost in 
microsoft.public.windows.server.active_directory, you are correct about 
that.

I've found a couple of interesting KB articles this weekend:

http://support.microsoft.com/?kbid=873059 (I've allready request and 
received the hotfix). This is an important one for our situation! Rus breaks 
when in Windows 2003 Forest Functional Level!

For other people dealing with an AD upgrade and using Exchange 2000/5.5

http://support.microsoft.com/default.aspx?scid=kb;en-us;825916 (Only when 
you have Exchange 5.5 as well)

http://support.microsoft.com/?id=321648

Hi,

I assume that you will remove the Exchange 2000 immediately after 
installing the Exchange 2003 server. So RUS may not be a problem. The 
problem occurs only on Exchange 2000 server in Windows 2003 forest.

Hope everything is going well with you. Have a great day!

Aha, no sir, assumptions can be dangerous :-)... they will keep running 
Exchange 2000 and bypass Exchange 2003 completely. But not to worry this fix 
will keep 'm runing. If there are any doubts about that please reply to this 
mail and then we will not raise the functional levels.

Have a nice day

Hi,

I have searched for related cases in our database. So far, I just find a 
few cases which indicate RUS may not work properly after raising the 
functional level. And the problem will not occur on every server. I did not 
find anything else:) Although the operation is safe, I still suggest you 
backup your DCs and Exchange servers first.

Hope everything is going well with you.

We've got all 14 servers involved backed up daily ... but we're never in a 
mood to realy need/use them.  I'll let you know the result when I pull the 
switch.
