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.

So im being forced to buy minecraft again? When I already had a "premium minecraft account." Migration is on hold and it says I can still play with my account, but how? It doesn't let me log in anywhere. This is honestly infuriating and makes me not want to support mojang or MC.
