Obviously there is no straight rename in SharePoint. you need to back up, delete and restore the site under a different URL...
I did this and have noticed some quirks with SLK...
1st -- Courses seem to be restored ok but in the my assignments web-part the "Site" column reads as "Unknown Site"
2nd is when attempting to delete an assignment it give me an error and logs this in the event log --
SharePoint Learning Kit Error
System.IO.FileNotFoundException: The site with the id 9c704f6c-5221-4325-8b69-70e9e1b2d13a could not be found.

Obviously it is looking for the site GUID of the old site. I have a feeling it is the same reason for both. Is there an easy way to correct this?
