If you have attempted to add a colleague to a previous Canvas course that is listed in Past Enrollments, you have probably found that the +People option is no longer available. This is because these are archived, read-only courses. You cannot add people to those courses. These courses are maintained in a read-only state to ensure that the content is not changed. You can still share this content with a colleague, but you will need to create an export package to send to your colleague or move the content to a sandbox and offer access there. Both options allow your colleague to use your content without compromising the original course.

NOTE: To ensure that the future course does not encounter a Gradebook zeros error, follow these "future courses" steps before copying a course.

Create an Export Package

As its name suggests, an export package is a file (i.e. package) that includes all content exported from a Canvas course. You can create an export package and email it to a colleague to be imported into their course or sandbox. To create an export package to send to a colleague:

Open the course from Past Enrollments (click Courses; All Courses; and the course name in Past Enrollments)
Click Settings
On the right side, click Export Course Content
Make sure "Course" is checked and click Create Export
The export process will begin. For a large course, this may take some time. When the process is complete, you will receive an email notice.

Now that you have created the export package, you need to download it and send it to your colleague:

Click the View Exports link in your email, reopen the export section of Canvas using the above process, or refresh the export page if you are still there.
At the top you will see a link that says "Course Export from X"; click that link and the export package should begin downloading
Once the file is downloaded, you can email it to your colleague; it should save in your computer's default download folder

Here are instructions you can send to your colleague, so they can use the export package you send:

Download the export package to your computer
Open the sandbox or course where you will import the content
Click Settings and then Import Course Content on the right
From the drop-down, select Canvas Course Export Package
Click the Choose File button and select the export package you downloaded from the email
Check the “All Content” box
Click Import; it will let you know once the import is complete

Move Past Enrollment Content to a Sandbox

To transfer content to a sandbox, use the same process you would use if you were copying a course from one semester to another:

Open the sandbox
Click Settings
Select Import Course Content
Select Copy a Canvas Course
Select the course in the drop-down
Check the “All Content” box
Click Import; it will let you know once the import is complete
Once the import is complete, add your colleague to your sandbox by clicking People in the course menu, clicking +People in the upper right corner, and adding them using their email or user ID (Login ID). Add your colleague as an “Instructor” (in the Role drop-down) to give them full access to all materials.

If you need an additional sandbox, you can request one by following these steps:

Go to: https://ituc.service-now.com/
Login using your UC credentials.
Click Support & Services
On the left, click Teaching and Learning from the menu
Click Canvas
Under “How can we help you?,” select Request Something
Under "Canvas Request Options," select Request a Sandbox
Enter the number of sandboxes
