What you need:
A copy of Grand Theft Auto V on Xbox One.
Previous Grand Theft Auto Online character and progression data on either Xbox 360 or PlayStation®3.
Note: When transferring from Xbox 360 to Xbox One you must use the same Gamertag. A new Gamertag on Xbox One cannot be transferred to from a different Gamertag on Xbox 360 since your character’s progress is tied to the Gamertag.
A Rockstar Games Social Club account. If you do not already have a Social Club account, you will need to create one. Click here for info on creating an account.
An Xbox Live Gold account.
If transferring from Xbox 360, your Social Club account will need to be linked to the Xbox Live account used to play GTA Online on both systems.
If transferring from PlayStation®3, your Social Club account will need to be linked to the PlayStation®Network account used while playing GTA Online on PlayStation®3 and the Xbox Live account used to play GTA Online on Xbox One.
