Moodle allows course instructors to merge the participants from two courses in Moodle into one course site. You may want to do this for cross-listed courses or lab sections.
Once you merge the participants lists into one site, just hide the site you are not going to be using and tell students enrolled in the hidden section to access the class materials via the site that is not hidden.
- Open the course into which you wish to add students and click the Turn editing on button.
- From the Administration block, click Users > Enrollment Methods.

- From the Add method drop-down menu, select Course meta link.

- In the Search box, find and select the course name, whose roster you wish to add to the current course.

- From the Add to group drop-down menu, select Create new group.

- Click the Add method button.
- To view all the participants in the class, click Users > Enrolled Users from the Administration block.
- Participants added from the other section will be listed in a group with the original course name.
