on a 2008 domain I am going to migrate from my single exchange 2003 to 2010. When I install the new 2010 server do i use the same ‘Exchange Organization name’ as my existing 2003 server? Will it even ask me if it’s not the first server?
Secondly all my clients have outlook 2007 configured with an exchange server IP of 10.x.x.1 (which currently resolves to the 2003 server name), i plan to change the IP of the 2010 server to this .1 address after removing the 2003 server (and turning it off) will outlook update itself, or hang looking for the old server name? should I leave a host entry in dns for the old servers name to the .1 address just in case?
