"Downgrade" from Halion 4 (Edu) to Halion Sonic 2?

Yes, I agree with you guys. The upgrade from H4 to H5 (with HS2 included) is the obvious choice, but at the moment my budget for plugins and stuff is low, so I thought that maybe I could “downgrade” from H4 to HS2 without paying anything (I think that would be quite fair), and then, in the future, if I’ll really need all the extra features of H5 i’ll do an upgrade from HS2 to H5.
