Wavelab LE 7 to LE 8?


I’m a new user of the Wavelab LE series and I have a few questions regarding upgrading.

Going out on a limb I assume that LE stands for “Light Edition” and that there is no way to upgrade directly from say Wavelab LE7 to fullfledged Wavelab 8 with any reduction in price (it’s mainly for Wavelab 7 to 8 right?), but is it possible to upgrade from Wavelab LE7 to LE8? I’ve searched the Steinberg main page, but couldn’t find any reference to it.

Or is the LE series primarily software that tags along with some selected hardware like say mine which was the CI1?
