A course import package is a ZIP file of exported course content. When you import a course package into an existing course, the content of the package is copied into the existing course. Import packages don't include student enrollments or data, such as discussion activity and grades.
You don't want to upload an exported course package that you've edited after it was created and downloaded. If you open the ZIP file and change any of the files in the exported course package, the result will be unstable and unpredictable behavior when the course is imported.
Import a course package
Control Panel > Packages and Utilities > Import Package/View Logs > Import Package
On the Import Package page, browse for the course package on your computer. Select the course materials to include and submit.
About content areas
Content from content areas appearing on the course menu that have the same name in the package as in the existing course will be added in the same content area. Nothing is removed from the course and replaced with content from the package. Imported content is appended to existing content in the same content area.
About discussion board forums
Include starter posts for each thread in each forum (anonymously) or include only forums with no started posts in the course copy.
About course links
Links to parts of a course that aren't imported will break when the links appear in the destination course. For example, if a link to a test appears in a content area and you choose not to copy tests, the link to the test will break.
About delegated grading
When you import a course without enrollments into an existing course, the delegated setting is brought over as enabled for all existing delegated grading assignments. All current users who can reconcile are also set to grade all submissions.
About attendance data
Export/import creates an attendance column that you can't delete, but no attendance data is added.
