Games : Will I have Dark Souls 2 and Dark Souls 2: Scholar of the First Sin if I do the upgrade? Will it include the DLCs?

I was looking at Dark Souls 2: Scholar of the First Sin and curious if I would loose my copy of Dark Souls 2 if I upgraded to the DX11 version. Will Scholar of the First Sin also include DLCs, as I bought the Season Pass with the DX9 version of Dark Souls 2.

(Can you also make a Dark Souls 2: Scholar of the First Sin tag?)
