i'm upgrading when i get home this arvo just so i don't do anything i'll regret, "Gamestudio/A7 Commercial Upgrade from A7/A6 Extra" will also upgrade from old A6 Extra (like, if i didn't buy A6 Extra this year and so am not eligible for the free upgrade to A7 Extra)? i know it says "A7/A6" so it seems self-explanatory, but buying A7 extra gives you "A7/A6" so i just want to be absolutely sure
