Upgrade from Wavelab Elements 9.5 to Pro?

Hi!
I was not successful with my search hence I may ask a common Question again (and again):

is there a way to upgrade Wavelab Elements 9.5 to Wavelab 9.pro?

The shop only Shows me a generic update from “Wavelab Elemsnts” at 249 € which appears Little to overpriced if I already purchached a 9.5 Version.

421 Euros sounds more correct. If you are a student it would be less…

There is no upgrade from WL Elements 9.5 to Pro 9.0. 9.0 is no longer available since the current version is 9.5. Overhere I see € 479 from Elements BTW…
