Unfortunately, PC Migration is a one-time process that, once completed successfully, cannot be undone. Players who link and migrate from a different Battle.net account than desired may try again. To do so, players must link their intended Battle.net account to a new Steam account through Bungie.net and perform a new migration. Players who link and migrate to a different Steam account than desired must log in to that account on Steam in order to access their characters, Silver, and licenses. Once migration is initiated, these cannot be transferred to another Steam account.
Edited by FoxMikeLima: 10/10/2019 3:06:47 AMI would love to know how it's possible to have my one and only battle.net account be the incorrect one transferred to my steam account. Bungie, this is on your end, not ours, and the fact that your best response to us is to make an entirely new steam account for one game is absolutely absurd. I'd love to know which battle.net account was transferred to my steam account, because it sure wasn't mine. I requested my refund on steam while I still can, I'm out. Good luck.
