Changing levels, C++

I’m bumping this slightly old thread because I really need to know this.

Maybe I should ask a more general question: Does anyone have an example C++ project that includes changing levels?

I searched the templates (4.7 and 4.8) for things like “OpenLevel” and “ServerTravel” and found nothing.

The more I try to get it working, the more pieces seem to be missing. I get the feeling that I’m asking the wrong question or searching for the wrong thing because this is such a fundamental thing that I’m trying to do and there is no sample code to be found – not even in Rama’s code wiki. The only thing even semi-relevant that I can find there is this:
Game_Instance,_Custom_Game_Instance_For_Inter-Level_Persistent_Data_Storage
