I am trying to achieve the following:
We have three schools running three different Moodle Installations with students / teachers enrolled. And there is one central Moodle Installation where course content developement happens, this installation only have administrators and course creators enrolld.
So if for example we are talking about a Pre-Calculus Course for Grade 11 that is currently being used in all three schools, students have some quizes attempts, some assignments uploaded, etc. And in the middle of the year the course is decided to be modified. The modification happnes in that one central installation and then must be applied to the three child sites.
So the question is: how do I take the backup of the course contents ONLY (no user info) and restore it in the three schools without losing the quizez attempts and assignments uploads done by the students? I just want to update the course content (for example better lessons images or slight course rescheduling).
