Yes, this is my general recommendation. Try to do an install of Moodle from scratch. Experiment! In my videos, I do not show how to "migrate" your Moodle, which is what you will essentially be doing (going from old to new.) Hmmm, maybe my next video should be the one "How to Migrate your Moodle using only cPanel." Incidentally, as your Moodle grows in size, phpMyAdmin begins having problems. But by then, you might be willing to learn a little SSH.
However, since your current Moodle is working, don't destroy it until you have finished your experimentation, know a lot more of what you are doing, have a good backup, and are satisfied with your new Moodle.
