Cubase Elements 7 to 10 upgrade

hi, I have Cubase Elements 7 which I want to upgrade to Cubase Elements 10, how do i do that?
my second question is I have purchased Yamaha Genos Workstation, does it come with any copy of Cubase? I believe Yamaha and steinberg offer free DAW with Yamaha keyboards?

Thanks in advance!

It seems as if Elements is currently unavailable until the 10.5 release.
