Upgrade from XP to Vista in Parallels 4.0

Now that XP runs so smoothly in Parallels 4.0 I would finally like to try to upgrade to Vista. In Parallels 3.0 there was an "upgrade to Vista" feature included. How does this work in 4.0? I only have a Vista (Business) upgrade, not the full version.

 

Hello,

we have a KB article about this:
