[Server] Transfer server from SAMP to Open MP

[primat]

Hello everyone! I jsut found a gamemode where i've used to play back in the 2014 and i want to transfer it to openMP . And now i need to know to what i should pay attention ? Is there maybe some articles about it and what is the important point to do this ? Is there some major differences which i should also put attention to? How to transfer it in generall ? I would appreciate any help 

There is gamemode itself in a whole server build : Gamemode
