Microsoft Account with migrated Minecraft to it

If you had already migrated your minecraft account to your dad's account there is no way to migrate it again. According to Minecraft support, this migration is permanent.

This is assuming that's the migration you are referring to. But you can double check with Minecraft support.

For your Minecraft game, if you already have migrated your Minecraft account to a Microsoft account, it cannot be undone anymore. It will be permanently linked to the Microsoft account you used on the migration process.

The problem i'm having is that before migrating accounts I installed minecraft and made a new minecraft account under my microsoft name. I would like to delete that, and then migrate accounts

So back on late 2021 my account was hacked then migrated to a Microsoft account. I have already contacted Minecraft support but they said that they could not help me since my account was already migrated, and that I should contact Microsoft support instead. I still have the transaction ID and the name of the account.

Wait. So you are saying before you could migrate your minecraft account to your own Microsoft account someone else got into your minecraft account and migrated it to their own Microsoft account first?

Is that what happened?

Yes, unfortunately that’s the case
If maybe the hacked account was a Microsoft account, you could try to recover it

But as the hacker stole your Minecraft and then they migrated the account to a new Microsoft account
There is no way to know (from Microsoft side) which was the account used to migrate this Minecraft account
They only have the tools to work with Microsoft accounts
