Our QC team is migrating defects from many instances into a single, new instance using the import/export functionality of QC. Using this method I am told the defect history cannot be migrated. Does anyone know of any automated methods to preserve the defect histories? For instance, does anyone know if I can use Excel to write to the history table in QC (if so, how)? Or is there a way to automatically attach files to a defect (again, using Excel)? Of course, other suggestions would be welcome. Thanks in advance for the replies.
