Importing old Courses made in Aspen into Dogwood

[Thimoty Barbieri]

Hello all,

 we have several courses that we developed with an old Aspen version of Open EDX and exported in tar.gz. We are now re-installing Dogwood and tried to import these courses, but the import fails (The course gets created with the title only).

 Can you suggest a way, if it's possibile to re-import those old courses into a new version of OpenEdx?

Many thanks in advance
