Hi @shannon_cordova ...
Sorry to see that your question has been sitting out here for so long without a response. If you wanted to merge two courses together, it's usually a good idea to do this before the courses start. Since you had first posted this question back in August, it probably wouldn't be a good idea to merge the courses now (unless you've already found a solution on how to do this). Merging courses in Canvas is called "cross-listing". It moves enrollments from one course and puts them in another course. It does not move the course content...only the students. You can cross-list two or more courses together. For example, if you have two courses, A and B, you'll want to log in to course B and then follow the instructions in this Guide: How do I cross-list a section in a course as an instructor?. You'll be specifying course A as you complete the cross-listing. Then, when the cross-listing is complete, you'll log in to course A, go to the "People" page, and then you'll see students from both courses listed there. If you had a third course, C, you'd do the same thing...log in to course C, and then cross-list that with course A.
I hope this will help a bit. Sing out if you have any other questions...thanks! Take care, stay safe, and be well.
