Today’s the day! As part of making Minecraft: Java Edition even more secure, we’re beginning to roll out mandatory migration for some players. Check out our FAQs for all the info you need to know and don’t forget that we are here to help with your migration questions!

I have access to my old (not used anymore) email linked to the mojang account and i correctly receive the migration code but when i try to migrate to my active microsoft account (different email) all i have is a creeper that says "uh oh something went wrong"...

Go ahead and contact us at msft.it/6012wsDxQ with a screenshot of that error. We'll be happy to check that out for you! ^NS

Already done, they told me to try with another browser, tried with 3 different browsers on 2 different pc, still the same problem
