I am upgrading my email system from Exchange 2010 to 2013.  I have about 2 dozen mailboxes so my 1 mail server handles all functions.  I've installed 2013 into my network and migrated a couple test mailboxes over to it.  Email has been flowing properly to and from those mailboxes for over a week now.  All mail is flowing to and from the internet through the 2010 server still.  I am ready to point my firewall directly to the 2013 server and make it the internet facing server.
So my questions:  from what I've read, once I point my incoming email directly at the 2013 server, I need to create a new UCC certificate with the same FQDN I'm currently using ( on the 2013 server and move my remaining mailboxes.   My mobiles using activesync should not need to have anything done - they should pick up the change at that point - is this correct?  The desktops on the domain will automatically pick up the change as part of the move process - that is simple.  I expect certificate errors on the desktops until the UCC cert is created.  Anything else I need to be thinking about?
