4.1 Oracle Data Pump Legacy Mode Use Cases

Oracle Data Pump enters legacy mode when it encounters legacy export or import parameters, so that you can continue using existing scripts.

If you previously used original Export (exp) and Import (imp), then you probably have scripts that you have been using for many years. Oracle Data Pump provides a legacy mode, which allows you to continue to use your existing scripts with Oracle Data Pump.

Oracle Data Pump enters legacy mode when it determines that a parameter unique to original Export or Import is present, either on the command line, or in a script. As Oracle Data Pump processes the parameter, the analogous Oracle Data Pump Export or Oracle Data Pump Import parameter is displayed. Oracle strongly recommends that you view the new syntax, and make script changes as time permits.

Note:

The Oracle Data Pump Export and Import utilities created and read dump files and log files in Oracle Data Pump format only. They never create or read dump files compatible with original Export or Import. If you have a dump file created with original Export, then you must use original Import (imp) to import the data into the database. The original Export utility (exp) can no longer be used.
