My team has created a VR game for the HTC Vive using UE 4.18.

Is there a way to create a mobile version of this VR game? Or is the better choice just to make a copy of this Unreal Project and use this separate project to make a separate game for mobile?

The only issue with the latter option is if I make changes to the original game, I would have to make a copy of this new project version every time.
