I have a exchange server with 2003 windows and exchange.  The server is at the end of its life cycle and we have purchased a brand new exchange server and will load the same software.  How can I install the server so I do not have to make any changes to the clients computer.  Do I name it the same as the old box?  Do I keep the same IP address?  Also how do I transfer the mailboxes over.  Thanks.

Same name, same IP.  Dismount the database, Move the database, and mount it.  That should be all.

Load the new server, operating system, patch it all up, use a different ip address, and and a different server name...
install exchange make it part of the existing site / organization, patch it all up...
you will then need to move all the services to the new exchange server, public folders, replication, maili connectors.
you will need to add a new dns records to your external dns for your new exchange server, and new nat translation in your firewall, and access rule to allow that server to send and receive emails.
when you are comfortable with all that create a new mailbox on the new server and test sending and receiving email.
once that is good, then you can just select mailboxes and use the move tool to move mailboxes to the new mail server...

The other option that would make things easier, is using software like Acronis to get a bit for bit image of the current exchange server and put it on your new server.  This would be the safest way with the least amount of planning involved.  If you create a new server with the same name it will have a different SID and may cause other issues.  

Peralesa's post will work and is a good way of doing it, but you have to take into consideration any unique settings that you might have in your exchange environment.

is there a good step by step article about this.  I am confident I could do this but I don't want to miss a step and have down time.

I believe the backup solution should work.  Downtime is probably inevitable, but how much is relative to your level of preparation.  Does your current email server have multiple partitions? ie. c: for OS, d: for logs, e: for databases?

doing a migration from one box to another box, would be the option with minimal to no down time...

Why spend so long doing email signature updates?

Do you spend loads of your time carrying out email signature updates? Not very interesting are they? Don’t let signature updates get you down. Let Exclaimer Cloud - Signatures for Office 365 make managing email signatures a breeze.

the only conditions that might exist is the media you are mounting the backup into might be different than the one it came from (partition size, drive letter, etc).  you will need a product like Acronis Universal Restore for that.

Here's a guide you can follow for your migration.

As Peralesa said, you'll have to use a different name and ip on the new exchange server.   This would give you the least amount of downtime.  As far as not having to touch each client PC, as long as the old exchange server is coming off the network, you can create an alias (cname ) in dns pointing the old exchange server name to the new server.

When he moves mailboxes using the mailbox move tool, it will be transparent to the clients.

I experienced the issue of the workstations not recognizing the new exchange server after the migration with one clients network, so I've always taken the extra step.  Maybe it was an isolated incident? I'll have to test it out again.  Thanks Peralesa! :)
