Upgrading from Windows Server 2003 to Windows Server 2008 with Exchange Server 2007

DON'T DO IT!

Doing an in-place upgrade from Windows Server 2003 to Windows Server 2008, on a server where Exchange Server 2007 is installed is not supported.

And it WILL break things.

Your first clue that things will go awry is that you can't do an in-place upgrade when PowerShell is installed. So, if you ignore that clue (what? you need to be hit upside the head with a bat?) and remove PowerShell (can you imagine what removing PowerShell does to Exchange?) - the upgrade will proceed.

And guess what? After you are done, Exchange WON'T WORK.

You'll have a major recovery on your hands to get back to Windows Server 2003. In order to move from Windows Server 2003 to Windows Server 2008, you must use the move-mailbox method of migration.

Until next time...
