It's not a difficult thing to do, providing you go around it in logical and safe process.
If your changing like for like, it's normally at matter of making a little diagram and or taking a picture of what you have making notes of connections etc.. and copy that, but beware not all switches are marked up or configured quite the same.
If you go in wiki and search through the electrical section, some good pointers and tips.
But one of if not the most important things to remember is be safe, safe isolation of systems and circuits is paramount.
