Xbox – Character transfer from Xbox one

According to the information from Rockstar Support found here, You can transfer your progress to next generation consoles(Xbox one, PS4) and to a PC with the help of your Rockstar social club account. They have not mentioned about character transfer from PS3 to Xbox 360 in the provided link.

You can give it a try if you want with the procedure mentioned in their support link which I have given but, you will have only one chance and there are lot of limitations. Proceed at your own risk.

You can also post a question in Rockstar support for a definitive answer for your question.

No, not directly.

As always, there is a "workaround". You can challenge a friend to a match (arm wrestling preferred because it doesn't take long), bet 10k and let him win. So he gets the money from you. After that, you log onto the other character and do the same again, he bets 10k and lets you win.

Of course, it takes a while, but it's the only known way to me how you can transfer money.
