I am about to migrate my moodle from 1.9.16 to 2.3.3 but there is still something that's keeping me from migrating.
Up until now, once a year I move all course files (lessons, assignments, foro attachments and so on) from my web server to a backup copy. I need to do that because I have to pay for any extra disc I use. Besides, I want to keep the courses structure so I can keep students enrolments, grades, etc...which is quite necessary for my organization. That's why I can not delete old courses.
My question is, how can I move all those files out of the repository in one go without deleting a course?
Is there any moodle function that I can use?
Thanks in advance.
