Convert a Non-VR game to a VR game.Re

Hello everyone.
Currently I have a non-VR game which is played on Unity-XBOX ONE platform, If I want to convert this game into a HTC Vive VR game, what should I do?
Please help me, I can’t find the answer on the Google.
Thanks in advance

Hi,

you should hire someone to do it then… or what is actual the problem you have there?
