I have an Exchange Server 2007. I'm trying to install Exchange Server 2013 on another server so I can then migrate mailboxes, etc from 2007 to 2013 and remove the 2007 server.
My install fails because it says I still have an Exchange Server 2003. I had 2003 originally but it was uninstalled a couple years ago. I saw items regarding using ADSIEDIT to remove but when I go into it, under CN=Servers, I only see my current Exchange 2007 server listed.
Any suggestion on how I can fix this? Thanks!
