How to migrate from one 2003 Server DC to a brand new 2003 Server DC

I need to replace a Windows 2003 server with exchange 2003 with a NEW Windows 2003 server and most likely Exchange 2007.  What is the easiest way to do this?  I've read lots of answers with some ideas.  Is there a step by step list available that would assist in this?  Would it be easier to stay with Exchange 2003?   This may happen in July.  If 2008 is out then, would that be better.  Would it be safe enough since it's brand new?

Yes, we are keeping the same AD/forest.    The current machine is 32 bit and I am aware that Exchange 2007 must be on x64.    What does it mean "greenfielding"?
greenfielding == starting from scratch

the term relates to the practice of building on an unused green field site, as opposed to brownfielding - which is the re-use of previously built-on land

Exchange 2007 does require a 64bit OS

But as far as moving from one DC to another - just run dcpromo on the machine you want to make into a new DC, add it to the domain, and once installed, use ADUC to move the FSMO roles to it

then you can demote and retire the old machine

Has anyone used the Acronis products to restore the whole thing?  What are your feelings on using those products?
Restore Exchange 2003 backup to Exchange 2007.  Siorry, it is not possible as there is architectre difference between Exchagne 2003 database and exchange 2007 database.

Hence the above updates will form your solution.
Back after extended absense.   By doing the above steps, I should not have to rejoin all the workstations to the domain, correct?    I will have to re-install any server programs though correct?  If I want to keep my server the same name, at what step is the old server named something else and the new server renamed to the old server name?
