Can I port over maps/levels from source engine games? ie: Counter-Strike

I just installed Unreal Engine 4 and I have some experience with the Source SDK modding tools such as Hammer, a level editor for Source engine games like CS. I am curious to see if there is any way to port a map from a source engine game like Counter-Strike over to Unreal Engine 4. Thanks.

Doubt it, either way my guess is that it’s a question you should ask the Hammer community, if you can export Hammer levels into any common formats like fbx.

Question answered after an extensive googling session. It is a plugin called Hammuer.
