deinstalling Exchange 2003


I just Installed a new server that is running exchange 2010 on server 2008. I moved all the mailboxes over from the older server that is running exchange 2003. and the New server has taken all the roles over  that the old server had.

Is there a way to check if the server has taken all the roles? After this Do I just deinstall exchange?

Also the old server was acting  as DC on the network. How Do I make the new server the primary DC? so  then I can decommission the old server completely?

Thanks Martin

first please follow carefully this 4 parts tutorial it is from 2003 to 2007 but the same applies to 2010

after you finished all the steps yes you can simply uninstall exchange even if it is a domain controller.

now if the server on which you have installed exchange is NOT already a DC do NOT promote it to a DC or you might break exchange

I did dcpromo before I installed exchange.
Did that make it the primary DC?
AkhaterSolutions ArchitectCommented:
There is nothing called primary and secondary DC when talking about Active Directory. All DCs are more or less equal

make sure your new DC is running DNS and that all clients are pointing to it as their DNS server, also make sure to set it as Global Catalog if you don't have any other GC on the network (a part from the one you are about to uninstall)

then you can demote the old one safely.

However do NOT demote it before uninstalling exchange from it

AkhaterSolutions ArchitectCommented:

it seems to me the problem is that this wont work because I only have the 64 bit version of Exchange 2010.

Do I need to get a hold of a 32 bit version to make this work, or is there actually a 32 bit version out there?

went well

there is only 64bits of 2k10. run the setup/pl from the server that is running 2k.10
