U could probley transfer the data to the 20gb when ur done

About 10 years ago I created my xbox account under my dad’s email. Now that i have my own, I’d like to transfer the data to my account but don’t know how. Any help would be greatly appreciated.

You can't. Nothing is transferable between accounts.

Nothing can be transferred between accounts.

That wouldn't be possible. The data transfer cable is only meant to move data between 360 hard drives in the event that you get a new one. Xbox data is not meant to be seen by a PC and transferred between the 2 so you wouldn't be able to get anything from
the PC into a 360 game without violating the terms of service.

Oh okay! So it was just a local account which was then turned into a Live account by setting up Xbox Live? That makes a bit more sense now. Yes, the information on the account can be changed at
https://account.live.com. You'll be able to manage the login email (Aliases), contact information (Security proofs), and general user information from that link. As for changing the Gamertag, yes this does
cost money. You can do this from the Xbox console itself, this link should help:
