If you are allowed to create Canvas courses, you can copy a course and create a new course shell. Copied courses are added to the same subaccount as the course that is copied.

Courses should be copied when you want to use or repurpose previously created content including course settings, syllabus, assignments, modules, files, pages, discussions, quizzes, and question banks. You can also copy or adjust events and due dates as well as bulk migrate quizzes from Classic Quizzes to New Quizzes. You can also copy or adjust events and due dates. Not all content can be copied as part of a course.

When you copy a Canvas course using the Copy this Course button, you will be added to the course as an instructor automatically.

Learn more about the Course Import Tool.

Notes:

Course imports may not include all content. For more details, please see the import content section in the Canvas Basics Guide.
Importing a course more than once may have unintended consequences. If you import content into a new course, edit the content in the new course, and later import the previous content again, the imported content will override the existing content.
If the Copy this Course button does not appear in Course Settings, this feature has been restricted by your institution. However, if you already have access to a course shell, you can copy a course through the Course Import Tool.
Copies of existing Canvas courses and course files reference the original Canvas course file quota and do not count against course file quotas.
If you copy all content or include course settings in selected content, the grade posting policy from the original course will override the grade posting policy in the new course. Additionally, imported assignments will retain their assignment posting policy from the original course.
If you are unable to find your course, it may be located under Courses in the Global Navigation.
When a course is copied that includes a new quiz with an item bank, the item bank is shared with the new course automatically.

Open Course

In Global Navigation, click the Courses link [1], then click the name of the course [2].

Open Settings

In Course Navigation, click the Settings link.

Copy Course Content

Click the Copy this Course link.

Create Course Details

Enter the Name [1] and Course Code [2] for the new course. The name will be displayed on the Course Home Page and in Conversations. The course code will be displayed at the top of the Course Navigation menu and in the course card in the dashboard. Course code is also referred to as the reference code or short name.

Enter the Start date [3] and End date [4] for the new course.

Note: If the current course includes course override dates in Course Settings, the Start and End date fields will be populated with those dates.

Select Migration Content

To import all content from the course, select the All Content radio button [1].

If you want to select specific content, click the Select specific content radio button [2].

Note: If you select the specific content option, you are required to select the content you want to import; this action cannot be cancelled.

Bulk Migrate Existing Quizzes as New Quizzes

If allowed by your institution, you can bulk migrate existing quizzes into New Quizzes by clicking the Import existing quizzes as New Quizzes checkbox.

If your institution enables the quiz migration feature, question banks linked via a question group in Classic Quizzes will migrate to New Quizzes. If the quiz migration feature is not enabled by your institution, questions from question banks must be individually added before migrating to New Quizzes.

Notes:

New Quizzes does not include a survey feature. Therefore, surveys migrated from Classic Quizzes come over as standard quizzes in New Quizzes.
After migration to New Quizzes, multiple dropdown questions display as matching questions.
Text No Question questions migrate to New Quizzes as Stimulus questions. An instructor must add a question in order for it to display in a quiz.
Question groups with manually created questions will migrate as item banks in New Quizzes.
If a quiz is migrated multiple times, Canvas uses smart merging to decipher the question bank content that should be retained. This process helps ensure all content is retained, such as in cases where multiple users may be making edits to a quiz at the same time.
Practice quizzes from Classic Quizzes can be migrated to New Quizzes. Once migrated, by default, the practice quizzes are displayed as zero points possible and are hidden from the Gradebook and Grades page.

Adjust Events and Due Dates

If you want to adjust the due dates associated with the course events and assignments, click the Adjust events and due dates checkbox.

Copy Blueprint Course Settings

You can copy settings from a blueprint course into another blueprint course. Copying blueprint settings applies the same lock preferences to objects as the original blueprint course. To copy settings from a blueprint course, click the Copy Blueprint Course Settings checkbox.
