The Course Upgrade tool is one of the new DesignPLUS Course Tools that can only be accessed from the Settings page in the Canvas course.
If you are unable to see the Course Upgrade tool in your Course Settings, make sure that you have the new DesignPLUS sidebar loaded. If your Legacy sidebar is loaded, the tool will not show in the Course Settings.
To switch versions from Legacy to the new sidebar, please see our User Guide: Switching between Versions. Users may need to use the keyboard shortcuts alt/option+shift+d to open the sidebar, if it is hidden.
Also, please note that institutions do have the ability to disable the Course Sidebar (where the Course Upgrade tool is found) from within the Account Settings of their Customizations courses. If you have ensured you have the new DesignPLUS sidebar loaded and still cannot see the Course Upgrade tool, you may need to reach out to your Canvas/DesignPLUS administrators.
