No, you cannot transfer a profile from one Xbox account to another. Xbox profiles are tied to a specific Microsoft account, and while you can change the email associated with your account, the profile itself cannot be transferred. If you want to use a different account, you would need to create a new profile and manually re-add any friends or achievements.
you carn't
No
You can't if you have an other xbox account. I tried already but I can't because I locked myself out of my Xbox cause I didn't remember the password so you have to make a new xbox account and you don't get to have all you're saved data.
no my friend tried but he couldnt so you cant transfer information off your hardrive to another hardrive
No, I do not think this is possible. Plus, I'm sure it would corrupt the data that is the original one for account b and then use account a's Xbox Live data. Not only this, I know it's impossible to have save-data and other stuff used on another account when it's account a's information.
Yes, simply connect the memory unit to the new Xbox and sign in with the account.
If you have a Xbox live Gamer profile, you can just recover it on the new Xbox. If you are not online, you will need to buy a transfer cable.
This question is better answered by a customer support member from Microsoft's team, however, I think your best answer would be that it not be possible if a membership has already been added to an account.
Yes, your Destiny profile will transfer between the Xbox 360 and Xbox One. This will work the same as Call of Duty Ghosts.
When you activate Xbox live, you will need to activate it on a Xbox profile, there is no way to transfer the membership to another profile. The game saves etc are the same, all progress has been done on that profile, which means even if you did transfer a saved game, the saved file will be corrupt because its not in that profiles name.
No, you can, because microsoft took off live for the original xbox
Yes, they both utilize your Microsoft account, therefor you can have the account on both your Xbox 360 and your Xbox One. You will just have to bare with being prompted with "This account was logged in on another console" each time you switch from the 360 to the One.
