This is my situation...I created a second domain in an existing domain environment. I want Exchange 2010 to manage email for both domains, domainA and domainB. When creating an email policy for the new domain, it complains about detecting a legacy exchange server. My predecessor upgraded from 2003 to 2010. Exchange 2003 was installed with DC, DHCP, DNS, thus, the physical server is still online, but mailboxes were moved to 2010.
My question is, how can I verify it is safe for me to delete the legacy server from adsi? if an error is made, what is the best way to back up what I'm going to edit/remove?
Thanks in advance!
