Need Some Tutorials For Someone Moving From Unity 3D

Hey Guys!
I have been keeping my eye on Unreal Engine 4 for quite some time now, and I finally want to dive into it. My question is, what is a good tutorial series for someone that isn’t new to game development, but is new to UE4. I have used Unity 3D for several years and still enjoy the engine (I just want to diversify my knowledge), and I am also learning 2D game development with DirectX using a book. So I’m not afraid of programming.
Thanks!

I did stumble on an entire Youtube playlist dedicated to this topic about a week ago but I can’t locate it. Anyway, these should get you started:
