New Exchange Server, Changing IMS?

[Coldfuzion]

We are in need of replacing our current Exchange Server and have created a secondary exchange server insite. It has synced up to the main (old) one, we have moved all the mail boxes and public folders to it just fine, and in testing, are able to send/recieve through it.
It will have a diferrent name, which is fine, as we will deal with the mx records as needed.
How do we now get it to have it own IMS (its currently showing the IMS name of the original server)? And, is this the same as getting it to be the Bridgehead server? Once this is complete, can we then bring down the exchange services on the original server?
Thanks in advance.

I think that's all to it. Once you create the IMS on the new server, point port 25 to it and enable OWA (if you have it), you look to be sound.

Do a test, bring down your old exchange server check to see if email still flows, if it does, remove the old server from the new server and take 'er offline.

You need to check to see if the old server has first server in the site roles before removing it, and if it does reallocate them to the new server first:

Make sure you set the new server to be the prefered public folder server in the Priv Information Store setting of BOTH servers, and wait a few days (clients cache this info).

Bridgehead servers hold connectors to other sites - if you have any messageing or DirRep connectors to other sites, move these over to the new server before removing the old server.

Also, create a new IMS on the new server and copy all the settings over from the old to the new, before you remove the old from the site (in fact I'd just turn the old server off, to see if the new server survives okay without it - then if not, you can just power it back up again and fix any issues).
