Migrating to a new Exchange 2010 Server

Hello - we're running on Exchange 2003 and will be migrating all mail to a new Exchange 2010 server with a new server name this weekend.  We intend to swap IP addresses on the old and new servers, so we can keep the same IP address and not change that in the firewall for incoming traffic, but what we're wondering is if the new name will cause reverse-lookup problems at all when the new server under another name sends email out to the Internet with the same IP address as the old server?  Or will we be ok on that?

Thanks

You mean just a different physical name?  Or a change in the domain name?

If lets say the physical exchange server name changed from Exchange1 to Exchange2 there should not be a difference.

As long you have configured the SEND connector with the correct FQDN, they you are fine. Don't worry about the Receive Connector.

Yes - just a physical server name change, but still in the same domain as before.  But - it's the fact that emails used to go out from "Server A on IP A" and now it'll be coming from "Server B on the same IP A" that I wasn't sure about.  So we should be fine then?

The world doesn't care what your internal server is called. As long as the FQDN is correct then you are fine.

ok cool.  

say - you guys wouldn't happen to know if there's a way to COPY my 2003 mailboxes over to my new 2010 server, without moving them - I want to get a head start on the 60G of mailbox data, and also wonder if this would allow me a way to abort the migration and revert back to the 2003 server if something goes wrong this Friday night?  I see instructions for moving, but not copying.  If not, I'll open another thread.

Thanks for your help
