Symptoms

An Export bundle was created using the 12c Migration Tool (bi-migration-tool.jar). The 11g Production web catalog was over 8GB in size.

On OBIEE 12c, an Import was performed using the BI Migration Script (migration-tool.sh) to import the 11g data (contained in the Export bundle) in to the 12c system.  The import failed and the following was observed in the migration-#.log file:

SEVERE: Import failed: Plugin metadata -- oracle.bi.migration.plugin.metadata.TransformBarException: Transformation failed. Check logs for failure messages.
oracle.bi.migration.importer.ImportProblemException: Plugin metadata -- oracle.bi.migration.plugin.metadata.TransformBarException: Transformation failed. Check logs for failure messages.
