Import project from RoboHelp to FrameMaker

Hello,

I have a project that I would like to import from RoboHelp 2017 into FrameMaker version 10. I have two major questions that perhaps you can help me with:

1) Are these product versions compatible or do I need other versions that would enable the content import?

2) How do I achieve the actual import? What is the step-by-step process/procedure in FrameMaker?

Thank you kindly,
