Importing mappings in Advanced mode If Advanced mode is enabled, there are two additional options: Import > From Database... and Import > From Classic File (.xml).... To import from database: This option is only available in advanced mode, and works in a similar way to import from server. Use this option only if you need to import mappings from a Mapper Database for an earlier version of IEC. To import from classic file: This option is only available in advanced mode. Use this procedure to import classic xml files located in a folder with the associated input or output schemas.
