For security reasons, we are no longer maintaining any Moodle archive servers, since they have been flagged as a security risk (running unpatched versions of operating systems, plugins, etc.). Those past courses do exist as Moodle archives, saved on a cloud-based server.
If your course no longer exists on the main Moodle server (which currently holds four years of courses), you'll need to send an email to DPS, asking that the older course be retrieved from a course backup. In your email message, please mention the Course short name, if you remember it (for example, PSCY100-01-FA2020). If you don't remember the particular section number, please at least provide the course designation (for example, PSYC100) and the semester when it was taught (Fall 2020, in our hypothetical example). Please let us know as well the name of the current course into which you want the content copied.
Please contact DPS if you have any questions about finding or copying over past Moodle courses.
