I will have to purchase the battle.net legacy dlc?
I have to get over it?
The migration period from Battle.net to Steam ended on December 1, 2020, and can't be extended or turned back on. It's now impossible to transfer your account, purchases, and characters over. From September 2019-December 2020, many emails, social media messages, and in-game notices were sent out to inform players that this was occurring. Destiny 2 is now free-to-play, and the Red War, Curse of Osiris, and Warmind campaigns and content were added to our Destiny Content Vault. For more information, visit http://www.bungie.net/Vault2020. If your account wasn't migrated over, you will have to create a new account on Steam with new characters if you'd like to play Destiny 2 again.
