Do you plan to install DC and Exchange again on the same server? That is not really good idea.

I agree with Davorin.  Having Exchange on a DC is only a good idea on an SBS where it's designed to be.  Exchange on it's own is a resource hog.  I would set up an Exchange server first and move Exchange.  Then remove Exchange from the DC.  There should be no reason to set up a new DC is you're on Server 2008 R@, but Then it's just a simple DC migration process.  if this is a small organization, have you considered  SBS 2011?

Thanks all ( Mr. superTaco & Mr. Davorin)

i acknowledge that it is not recommended from microsoft to install Exchange server with DC on the same server.

but i joined my company and i found this enviroment there.

let me sir explain what are really there ( do not be shocked like what happen to me ;) )

there is another Windows server 2000 DC, and all the Computers joined this DC (1500 users). the new DC (2008 R2) only to give the users accounts on exchange 2010.

by default this is not acceptable at all for any System administrator. ( !!!! )
so what i am thinking is to seperate the exchange server and move it to new server.
also i need to change the server it self so i have to move also the DC to another server.

for the old DC i will do migration to 2008 R2 and shift all the users to the new Domain .

this is what i am thinking.

please advise....

ah ok, now I understand.  I wasn't blasting you, and LORD KNOWS, I have been thrown into something like that.  If you have a 2003 DC, Make that the PDC and take the 2000 server out before anything.  then do an Exchange migration to a new server, with a proper decommissioning.  then the DC migration.  it sound to me thought that the 2000 DC might be a different domain.  To do anything with a 2008 server, 2000 can't be domain functional or forest functional level

Yes.  An Exchange migration is quite simple.  


That's for the install.

this is more for Exchange 2007 to 2010, but Exchange 2007 and 2010 are so similar, this should help you move.

Ms Exchange 2010 deployment guide - you will have here some more details:
Take an option for upgrade from exchange 2007.
On second SuperTaco link you don't need to go thru steps 1-5 because you have already done so at installation of the first exch 2010 server.
You will need to get and install new certificate, change port redirection on your router,...

Usefull links:

For moving DC:
Just install a new DC:

Move all FSMO roles to new server:

Remove old DC:

For moving users from W2000 domain (unfortunately as I understand it is different domain).
You will need to create new users in new domain, copy user domain profile to local user profile, remove PC from old domain, connect PC to new domain, copy previously created local user profile to new user domain profile... - it will take too much time!!!

Other option is using ADMT tool to migrate users, groups, workstations to new domain

There could be some other more appropriate method...

Yes, I know that you are not doing a exchange 2007->2010 migration, but I could not find an article for exactly your case.
As exchange 2007 and 2010 are really similar, I have posted migration guide and I have noted what steps you don't need to do - as this is not migration.
If I will find more appropriate article I will post the link.
