ID:19936 Partition '<partition_name>' is assigned to a Partition Database File '<qdb_name>' that was exported at the '<qdb_snapshot>' snapshot. This partition also has a preservation setting of '<preserve_snapshot>'. The preservation setting must be removed or changed to a snapshot later than '<qdb_snapshot>'.

CAUSE: A partition is imported with a QDB_FILE_PARTITION assignment, but a PRESERVE assignment is also specified on the partition at an earlier snapshot than the imported database.

ACTION: Remove either the QDB_FILE_PARTITION assignment or the Preserve assignment of the partition in the Quartus Setting File.
