I hope this has been placed into the correct forum and hasn't been asked to death elsewhere!

At present, I'm about to do an upgrade to the full version of Cubase 7.5 from my Cubase Artist 7 installation.

As I have upgraded some other products too, please let me know how I can (or IF I can) reactivate the licence keys to allow me to either sell on the product or pass it to a friend.

The outdated products are as follows:-

Halion Sonic (boxed) - I have purchased Halion 5 (boxed)to replace this software. Will Halion 5 function without Halion Sonic if I have the key reactivated?

Cubase Elements 6 (boxed) + Cubase Artist 6 upgrade (boxed) + Cubase Artist 6.5 upgrade (Download) + Cubase Artist 7 upgrade (Download) - I wish to remove all of these items in favour of the Cubase 7.5 mentioned earlier. Does each of these products carry it's own key or are they all rolled up into 1 licence key (as suggested by the eLicencer) - Can any part of this, or all parts be reactivated?

Thank you in advance for any help

Scott
