I've installed Exchange 2010 on one server with 10 mailboxes, 1 distribution group and done mostly basic configuration limits of Exchange. Later on it was decided to move it to Virtual Machine so I've installed 2nd Exchange 2010 server on that virtual server and both servers are now visible. First server has pop3 connector running that gets emails from external servers. There's no mx running yet as the server was on dynamic IP when setting up started. Now it has static IP so port forwarding will be done to point to the new exchange server.
I've started Local Move Request for all mailboxes, and it finished successfully.
What else should I do?
How I make sure nothing gets lost?
How do I remove 1st server permanently making sure nothing gets broken?
