Account Migration has not begun. There will be an in game message when it's your turn to move. Do not fall for any third party websites that are telling you to migrate NOW. They're trying to steal your information.

Hello, I want to change my email to my account, but I do not have access to the email anymore. Unfortunately, I don't know my transaction id because I bought a game card at a gamestop. Is there any way to recover my account before the migration? Thank you!
