I want to buy black ops 3 gold edition, while I have a disc of the normal version.

The reason why I am buying black ops 3 gold edition digital ,is because I am using remote control and I have a lot of DLC's (I have all zombie maps, I like to play zombies). My question is, will my data be save and is it still possible to move my DLC's to the digital game. Thanks for the person who knows the answer.
