Turning existing geomentry into a displacement map

[StarrLess]

Can someone direct me in the right way of how I turn a high mesh sculpted geometry object into a displacement map for a for a low-poly version? 

Google is only giving me options for Blender, C4D and Sketch up options to do this. For Maya to turn displacement into geometry.

I did all the sculpting inside of Maya

Take a look at the 'Transfer Maps' tool, that will do what you need 🙂
