Hi
I am afraid there is no such option, As the course is linked with different others table related to teacher, student.
You can try this way
There can be a single way to upgrade, I am not sure how will work though:
1. Delete all Guru and tables from the new site;
2. On the new site, put the old Guru files and old Guru tables - copy all from old to new;
3. Install over the latest Guru version;
In that way, the tables and columns we added in time will be installed by Guru automatically.
You will not be able to import a table over an existing table as you try to do; the above way should be the only way that this migration may work and may not if there is any error
