Not getting much joy from the partner support lines (always shut when I'm
free to call and their email responses just tell me to call them)! Anyway,
I'm hoping there is another Registered partner with the Action Pack
subscription who can answer my question.

Can the upgrade version of Vista Business that they ship be upgraded to
Ultimate using the online Windows Anytime tool? Previously, I've known that
retail, MSDN, select, etc versions are not cross compatible and cause all
sorts of hiccups if you install one and then try to use the media for another.

This is important for me as I expect to mainly be supporting Ultimate and
not Business, so currently have the 'wrong' version.

Thanks!
