Is there a way to export Shaders between projects? ( 4.10 to 4.9)

Hey, I am trying Export the files/shaders from one project to another but unfortunately the projects use different version of the Unreal Engine. (Was 4.10 and trying to import into 4.9)… I have tried using the migrate option but when I try and open the shaders or files that have been imported nothing happens. Is there anyway of actually doing this?

Sorry if this question is in the wrong section of the forum.

I saw this happening to me too, I’m wondering if there is a kind of failsafe like Maya and 3DS Max where you cannot go backwards in versions
