Transfer profile and gaming history to a different email / microsoft account

Sorry, but no. Nothing can be transferred between accounts.

You need to download both accounts to your Xbox 360 console and wait for 30 days before you can process the transfer of gamertag to different Microsoft email address.

After 30 days, you can already transfer your gamertag to different Microsoft email address.

Please open this link for the steps

So I guess a better question would be, are DLC licenses tied to the specific xbox live account that bought them, or the gamertag associated with that account?

If one transfers a gamertag using these steps (support.xbox.com/.../switch-gamertag-to-different-microsoft-account),
does that transferred gamertag have access to the download history of the account it was just transferred to?

Hi ne0matr1x,

Thank you for bringing this to our attention. At this point there is no way to transfer everything xbox related from one account to a different Microsoft account. Purchases and purchase history cannot be transferred over either.

What can be done is
changing the Primary email account to your sons email. However, this will cause issues if you use this Microsoft account for personal use.

Hope this helps.

Hi there!

This current email you're using, is it a 3rd party email or a Microsoft email? If that's a 3rd party email, it's only possible to transfer it from one account to another. If that's a Microsoft email, it cannot be linked/transferred or merged to a different Microsoft account. Either way, we cannot merge accounts.

Since your Minecraft is linked to a different account, it will stay there same as your other games and gamertag on your account from your console. What we can only do is transfer aliases or primary email addresses given that the email address is a 3rd party email.
