I found when migrating accounts when you go to select a microsoft account to migrate to but then select make a new account, it will make the account but then when it tries to migrate to said account it just 403s. The work around i found was make your microsoft account on microsoft.com and then to migrate without hitting create new microsoft account.
An easy bug fix for this would to just grey out the make new account button when migrating.
When i contacted mojang support they redirected me here, if i get redirected again i'm not going to contact them as they were not able to help me at all (I don't need help anymore as i found the work around myself)

Hi withheld, does this report describe the issue you experienced? WEB-5047
Yes, however it doesn't explain why it happens. The why it happens is when you try to make an account on the migration link it makes the microsoft account but then 403s, so then you have to go through the migration link again and use that account.
As WEB-5047 describes the same issue I've resolved this report as a duplicate.
If you have any other information that may be useful then please attach it to the parent report
If this is a dupe it's because i looked through 2 pages of 403s and couldn't find this at all.
