  <pre><code>Attach database failed for Server '...\SQLINSTANCE'. (Microsoft.SqlServer.Smo)
  
  Additional information:
       An exception occured while executing a Transact-SQL statement or batch.

            The database 'DBName' cannot be opened because it is version 782. This server supports version 706 or earlier. A downgrade path is not supported.
