I honestly don't know because I don't have any E7 L50 Silvers, but to qualify, you have to have E7 L50 characters of the rarity required (Bronze, Silver, Gold) and then fight your way up to Ares Ins. and then you can promote to EX and L60, which means that extra copies that you sold previously are now wasted :(
