Ok well I have my account on 2 xbox's. Ages ago I recovered it on my Dad's xbox. I just started playing again but on my account that was offline because I wasn't connected to the Internet and I earned a whole lot of acheivements. I know if I recover my account now it will delete the acheivements I earned but if I put the online account on a USB then put it on my Xbox will it merge with the other offline account and keep the acheivements? (THEY ARE NOT DIFFERENT ACCOUNTS, THEY ARE THE SAME BUT 1 IS THE OFFLINE ACCOUNT AND THE OTHER THE OLINE ACCOUNT). So can it be done?
