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

I agree with Roel about upgrading to H5 and using HS2. I don’t believe Steinberg would offer a “Downgrade” price and, even if they did, I don’t believe I would pay any price, other than zero, to get HS2 when, for $99, I could get H5 and work wih HS2.
