Legally speaking, you cant move purchased things to another account, thats called pirating, and is illegal, so im sorry, but youll have to buy it all back, or if you are really desperate, then you can attempt to contact microsoft's xbox support people!
I'd ask the Microsoft company, they helped me combine the two as long as I verified I was the owner of both accounts.
No I'm afraid there is not a solution as I have a xbox myself. I think Microsoft don't think its necessary to transfer data over because they allow you to change your gamertag, thinking that there will be no need to make a new account. I'm guessing there's a reason why you want a new account (other than changing your name) and unfortunately you can't transfer data to it.
You CAN'T, Achievements and everything else CAN NOT be transferred to another profile/account stats for that account are for THAT account, BEST thing to do - is just change your gamertag (it only costs 800 MS points, ) so I would just renew the account.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
