I just finished virtualizing our environment and the only remaining item to do is install and migrate over Exchange 2010 (vSphere 5.5). This environment is a sIngle site, single domain Exchange 2010 Standard deployment.
I have prepared the vm and have configured all the Exchange 2010 prerequisites and the Exchange readiness checks are all green. I am at the install stage. I have only ever built single Exchange server sites as I generally work with SMB 50-100 users. Am I correct in believing that email flow to the old production server should not be affected with the install of the second Exchange Server? Auto-discover does not do anything fluky does it :-) ? Am I also correct in thinking that will only come into play when I move the mailboxes over?
I will be using the same internet facing FQDN as our current exchange server (mail.mydomain.com). Is that OK as I intend to use the same MX record. The original Exchange 2010 server will be de-commissioned later. Will not be doing DAG or CAS Arrays.
