Transisting from Blueprints to C++.

Hi! I think there are many of out there, who have become intermediates/adepts with blueprints, maybe have some scripting experience, and are getting to the point in their project they realize things would be much easier, more efficient, and more robust if they made it in C++. For that would be helpful to have a video/doc page highlighting main differences and rules you can use to kickstart C++ gameplay programming with your blueprints -experience.
If this already exists, I would love a link. thanks!
