I have not really seen this question answered, but will it be possible to take a windows 2003 server installation and upgrade (downgrade?) to the upcoming LongHorn client and preserve your configuration and apps? Or you can ONLY upgrade to longhorn server which comes out later. Why do the server people always have to wait longer for the cool stuff, it's not fair!

I doubt it.

One is a desktop OS and the other is a server OS.

You can upgrade from client to server os, but not downgrade from server to client os

Though it is possible, I would never recoment this since windows 2003 is far more stable, than any version of Longhorn .. wich isn't even in beta stage yet.... You could try convertion your 2003 install to 2003workstation by use of register tweaks.. as can be done with NT 2000 and XP ....

there is a program call NTswitch.exe wich can do this ...

but you should be able to do it manualy to..

good luck - looking for a how to on google.

(they keep changing the site of it ... so im not shure where it can be downloadend right now.... )... good luck....
