Upgrade Domain first or Exchange first?

[Guest]

I have W2K native mode domain and Exchange 5.5 server. Management wants to
upgrade to Windows 2003 functional mode and install Exchange 2003 server.
Q. which should I do first, Domain upgrade or Exchange upgrade?

Domain first for sure, then exchange.

My order of preferences is:

1) Upgrade DC/GCs first to Windows 2003
2) Migrate from Exchange 5.5 to Exchange 2003

Note: I'm assuming you don't have the active directory connector in place.

The info you got before was wrong. You MUST upgrade exchange first.

When doing an in-place upgrade from Exchange 2000 to 2003, you have to
upgrade to Exchange 2003 first, then update Windows Server 2000 to Windows
2003 Server as Exchange 2000 does not run on Windows 2003 Server (see MS KB
321648 - You Cannot Install Exchange 2000 on a Computer That Is Running
Windows Server 2003 for further information).

actually now that i think about this and i think i know why the last comment
came in the way it did.... is Exchange 5.5 installed on a domain controller
or member server? (I don't install Exchange on dc/gcs. however your site
might and will influence the answer.)

 

[Guest]

Exchange 5.5 is installed on a w2K member server.
I also have the Exchange ADC in place and I have run Setup /forestprep &
setup /domainprep.
Is there a difference between ADC? (W2K3 VS Ex2K3)?

 

[neo [mvp outlook]]

Yes. The site needs to use the ADC from Ex2K3.

By the way, if you have already installed the ADC from Ex2K3... you have
already extended the schema in regards to Exchange. At this point I *think*
the only thing you have to be careful of is mangling of the inetorgperson
object. In any event since you have forged ahead, you might want to review
