I have an exchange 2010 DAG set up, We have decided to 'upgrade' to a single server set up as we are a smaller company and don't really need all those servers.<br />
<br />
I have set up a new server and would assume all you would need to do is a side by side migration. Has anyone had any experience doing this? <br />
<br />
Also is exchange 2010 base Capable to coexist with 2010 SP1? Should we do the migration while they're still base 2010 side by side or shouldn't it be effected by having it updated to 2010 sp1 and the DAG still be the base install?

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
