Fallout New Vegas Ultimate Edition + Collectors Edition

Hey well, i ve got the fallout new vegas collectors edition, so im guess im missing some DLCS, but the ultimate edition has all the dlcs right? So i was wondering, what if i ve got an used copy of the ultimate edition, are the dlcs on the disc? or are they downloadable?

What i want to do is, install the dlcs from the ultimate edition, and sell it, then i want to play my fallout new vegas from the collectors edition, but then i would have the dlcs, would that work? So i can sell the ultimate edition

no you will need the Ultimate edition disc.

just sell the disc from the CE
