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. ;-)
