Today I wanted to play Destiny 2 on my old account from Blizzard, where I saw that it wasn't there, so I go to the forums to see that there was a data transfer that I missed. I checked my email, and I saw no email alerting me of this. I spent way too much time and money on this account, just to have it taken away, now in my mind, this isn't my fault and I would really like to play again. Please respond I would really like my account.
The PC Move process was available for more than a year (August 2019 - December 2020) and the deadline was announced through multiple channels. It's unfortunate that you missed the window, but migrations from Battle.net to Steam are no longer possible. Note that all characters now start at 1050 Power, the Red War, Curse of Osiris, and Warmind campaigns have been placed into the Destiny Content Vault, and Legendary gear more than a year old has been sunset, so if you had taken such a long break, you would have been effectively starting from scratch even after migrating your Battle.net characters to Steam.
