Exchange 2003 to 2007 New Server Move

I currently have exchange 2003 running on an older server.  I purchased a new server and I am going to install exchange 2007 on it.  I would like the same server name on the new server as the old server if possible.  Granted I can't have both on the network at the same time if they have the same name.  Should I name the new server something like exchange1, join it to active directory, install exchange 2007, move mailboxes, kill the old exchange server, rename the new server and switch the ip address to the old name and ip or would that cause too many problems?  If that might cause problems would you just leave the name as exchange1 and just switch the ip address?  How would you go about the installation/configuration.  Any recommendations would be helpful.  I also wouldn't have to move the mailboxes as they are pretty much test mailboxes but would like the practice.

No you want. If you uninstall the old one, and it removes all its hooks into AD, then you won't have any issue with installing a new one with the same name.

Why same server name? If you put it in the same org, and move a mailbox to the new one (regardless of name). Exchange will signal Outlook to close and the user gets a popup box telling to do so.

RENAMING exchange servers causes the database to crash.This not recommended.OUTLOOK automatically detects the new mailbox server name you really dont have to worry about going to each client and reconfiguring settings.
THANKS.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

There is no reason to give the server the same name. When you move the users mailbox to the new server OL will contact the old server and see it has been move and the client will be redirected to the new server and its transparent.
All future connection will be configured to the new server.

what do you want to same name? There is not reason for it

I think I may have explained the question wrong.  What I want to do is get rid of my old 2003 exchange server completely.  I don't care about any of the mailboxes on it.  It was mainly a test server but it was in our production environment.  

I just wanted to know if I would run into any problems if I just unplugged the old 2003 exchange server, deleted it from active directory and then gave my new server box the same name and ip address of the old one, join it to active directory and then install exchange 2007.  Basically I want to start from scratch.

You will need to delete the mailboxes on the server, the uninstall the server and you will be good

Note: if you no longer have  2003 server and install 2007 you will be unable to add a 2003 into a pure 2007 envrionment.

Or you can just install the 2007 server move any resources and then remove the 2003 server...
