Hi, there: Ijoin an organization to do this Domino-->Exchange project. They currentlyuse Lotus Notes, decided to move to Exchange anddeployed test E2k3 into production AD(W2k3 with SP1),after that theyreformatted the hard drive of E2k3 server(NOTUNINSTALL E2k3 server!!), sothe production AD at this moment isstill populated with E2k3 object and the AD schema is still extended with E2k3 by E2k3 installation, Now they decided to use E2k7 instead of E2k3, The question is: 1): Canit be possible to run E2k7 setup on this productionAD without getting rid of the changein AD made by previous E2k3 installation? 2): How can we totally get rid of the change to AD made by previous E2k3 installation (In other word how can we cleanup AD and totally get rid of Exchange 2003 object in AD) and start installing first E2k7 in this environment? Appeciate your help.

I'd probably remove the Windows 2003 information from AD as cleanly as possible before deploying Exchange 2007. Start with this KB article: http://support.microsoft.com/kb/833396/en-us

Start with this KB article: http://support.microsoft.com/kb/833396/en-us Hi, Jeff: Yes, I agree it is best to totally get rid of E2k3 installed object from AD before first E2k7 introduction. this http://support.microsoft.com/kb/833396/en-usarticle is about removing E2k3 from a server, is there any article to remove E2k3 installation from AD? Thanks in advance!
