exchange 2010 migration - names, IP and outlook

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?

thanks, will the autodiscover feature ask the user for any information to be entered when they start outlook once their mailbox has been moved? if it makes any difference outlook is installed with the rest of office 07 using a custom msp file that specifies the exchange IP.

i think after the 2010 migration users who log into outlook for the first time will get their outlook profile created because of my previously mentioned outlook install method. i am most worried about users with exisiting outlook profiles who start outlook with the old server name as their mail server, will the autodiscover config sort this out too?
there is lots of stuff on net about leaving the 2003 server running for a few weeks, to allow users to be re-directed and outlook to change it's config. is this something autodiscover removes the need for?

No. There is not any differents.

It's about 2007 Autodiscover, but it almost the same for 2010.
