I have a single server setup and looking to move to a two server setup with one file/print and one Exchange. Currently everything is on one and it's not all that fast with the 60GB (and growing rapidly) private store. So I want to put in a server with 8GB RAM and RAID 10.

Was considering going to Windows 2003 Enterprise with Exchange 2003 Enterprise but figure it makes more sense to go to at least Windows 2003 or 2008 x64 and Exchange 2007 since Exchange 2003 won't do anything with RAM over 4GB.

Figure either migration would be pretty easy but I'm concerned about BlackBerry Enterprise Server. I know there are versions of BES that work with 2007 but I don't know if I would be running BES on the new server x64 server or the old x86 server.

Has anyone does such a migration?

Also how many users on Exchange and BES?

I was going to migrate one sacrificial lamb with a Blackberry to the new server and see how it goes.

Does the BES server itself run on the old server? I thought I read somewhere that the BES management application does not run. If it will all run on the 2007 server, I would be fine with that.
