I've seen a lot of people say that they upgraded their version of moodle, but I cannot seem to find out how they did this. I am currently using ver. 1.4.1 and would like to upgrade to ver. 1.4.4. Do I just overwrite all my files in my current directory and hope that the database will take care of my courses and users, or is there a certain process that I need to follow to upgrade. I've seen some people use CVS, but I have no idea how to use this. Thank you for your help.
