Hello, Thank you for your report. PC Migration is a one-time process that, once initiated, cannot be undone. Players who link and migrate from a different Battle.net account than desired can perform migration 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. https://www.bungie.net/7/en/PCMove
