slipping VISTA with Win 7 upgrade to make Windows 7?

[mikesw]

Can one slip a VISTA OS DVD with the Win 7 upgrade to make a Windows 7 OS DVD?

I realize one may only be able to slip a VISTA Pro with a win 7 Pro disk, but I'd think one

could upgrade any version of VISTA to any version of Win7. That is if I have VISTA Pro,

I should be able to upgrade to Win 7 Home (kinda of a downgrade) or to Win 7 ultimate

and to slip it too. The restriction would be x32 to x32 and x64 to x64.

Is this possible?

What about VISTA to win 2k8? or am i restricted from a server OS such as Win 2k3 to another

server type Win 2k8
