How do I archive student repos at the end of the semester?

Hi everyone,

When using GitHub Classroom, how do I archive repositories at the end of the semester?

Now that Classroom repositories are forks of the template repository, I can't move them out of my course organization without first detaching them. However, because the repositories are owned by the organization (as opposed to a specific user), there doesn't appear to be an option to detach them.

Leaving them in the course organization doesn't work, because that org will get too cluttered with repos. (I use some command-line tools that would break if the organization had thousands of old repos.)

I also don't want to create a new organization for each semester's instance of a course, because that would clutter my account with an increasing number of unused organizations.

Simply deleting the repos isn't the best option because then I'd have to nag the students to clone any repos they want to keep.

Have I overlooked anything?
