Hi everybody, I want to upgrade a Win 2003 server (32bit) to 2008 R2 on another clear partition while the system is running in production during the night. Is this possible ?

You cannot upgrade from 2003 32 bit to 2008 R2.  You can Migrate, but migration requires a second server.  You could migrate to a VM on another system and then reload the hardware with the virtualization platform and migrate the VM back to the hardware.  That would be the least disruptive to end users, though probably somewhat complicated.  Still, migrating to a virtual environment is, my opinion, both highly recommended and highly advantageous.

ok. Thanks everybody. If I install the windows 2008 R2 as a fresh installation in the not used partition I would like to have the choice to boot via boot-manager into either 2003 OR 2008 R2. I hope this works at least. So I can have a kind of fallback strategy. Ideas ?

I just bought the same HW (HP-Proliant). I have installed 2008 R2. I will change the disks from the old engine to the new server. I hope this works. ;-)
