Networking implimentation for a big project

Good morning, i was working for a game for 4 month now and i came to the point when i am going to make all of my scripts working online.
is there any other way beside tronsforming my function to rpcs ?
i’am really confused and i dont know how to transform the work to online script.
thank you for any help you will provid, tutorial, articles, anything…

Networking is a complex topic that takes time and good mental comprehension to get right. Jumping in straight away by trying to port an existing project is fraught with difficulties - instead I suggest start doing basic tutorials and learn how to network.
