Destiny 2 will be temporarily offline today for scheduled maintenance. Please stay tuned to @BungieHelp for updates.
Allo there, This help forum is how you get help from Bungie. Unfortunately you're out of time for transferring your characters and licences as that had to be done by Dec 1st 2020. They are now lost and if you want to play on steam then you'd need to start again and buy any content you wish to play. Keep in mind the base game and first 2 dlc was made free for all and has since been removed from the game. Forsaken is still part of the game however but you'll need to buy it again if you wish to play it.
