I am moving mailboxes with ESM to a new exchange server.
So far on the new server I have installed Windows Server 2003, patched the OS, installed Exchange Server 2003, patched the OS again, added DC, DNS roles, installed IIS, SMTP, and NNTP services.
Tonight I am going to move all of our mailboxes to the new server with ESM. When the mailboxes are finished I am going to export the SSL cert from the old server and set it up on the new server, then update my firewall policy so the NAT'ed external IP for mail points to the new server.
After that, I will need to move the FSMO roles and RUS to the new server - but that can take place any time after the mailboxes are moved and before the old server is decommissioned correct?
Does this sound right and am I missing anything?
