Blizzard has issued a final warning to Destiny 2 players on PC to migrate their account data for the game from Battle.net to Steam. The switch will finalise the break-up of Bungie from Activision Blizzard.
Is it not possible to copy/paste your OG game folder onto steam downloads and have it discover existing files? Might have a different steam folder name or something, but im sure that would make up a good brunt of it.
I copied the whole old Destiny 2 folder into my steam apps folder and it discovered around 54gb and only downloaded about 20gb. Haven’t played yet, visiting my brother, but while I’m here I’m just downloading and updating everything.
