Kids MS Account transfer of data

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

Wirey manc,

Unfortunately there is no way to transfer game data to a different MS account like that.

You can change what email is associated with an account to his email as long as it is not already a MS account and create your own account if you do not really use your account for much to do with MS but there is no way to transfer game saves and data between
accounts.

You can't transfer any kind of data among accounts. My suggestion would be to let the kid start on his own account to avoid future issues.

Your data wont transfer. As long as you know your Ms account login information you will be fine

You cannot transfer ms points or g points from one account to another one.

For your downloaded contents which you paid for, you can buy an HDD transfer cable and you can transfer datas to your new HDD.
