Dear suteja,

Thank you for your response. I tried importing the DBC archive in different Workspace versions and it unfortunately did not work either. (same error)

Other DBC archives of single folders from the Workspace can be imported to my current Workspace (I archived some folders of the old Workspace on a per folder basis in addition to the archive of the complete Workspace). Only the DBC archive of the complete Workspace does not work when importing and gives the error mentioned above.

Any other ideas?
