In 2019 I linked my Battle.Net account PlushPeaches#1415 to my older steam account. The Steam account linked is about to be deleted and I wanted to keep my Destiny (DLC) game since I have a new Steam account. How do I swap ownership?
Game licenses, and game data, are directly tied to the platform account. If you delete the Steam account containing your Destiny licenses, and character data, then you are also deleting all of the licenses and data. Bungie cannot transfer your licenses and game data between accounts, nor will Steam do so.
