How Data Pump Export Parameters Map to Those of the Original Export Utility

Here are the mapping of Data Pump Export parameters to original Export parameters. In some cases, because of feature redesign, the original Export parameter is no longer needed, so there is no Data Pump parameter to compare it to. Also, some of the parameter names may be the same, but the functionality is slightly different. The parameter are as 

Original Export Parameter	Comparable Data Pump Export Parameter
BUFFER	A parameter comparable to BUFFER is not needed.
COMPRESS	A parameter comparable to COMPRESS is not needed.
CONSISTENT	A parameter comparable to CONSISTENT is not needed. Use FLASHBACK_SCN and FLASHBACK_TIME for this functionality.
CONSTRAINTS	EXCLUDE=CONSTRAINT
DIRECT	A parameter comparable to DIRECT is not needed. Data Pump Export automatically chooses the best method (direct path mode or external tables mode).
FEEDBACK	STATUS
FILE	DUMPFILE
FILESIZE	FILESIZE
FLASHBACK_SCN	FLASHBACK_SCN
FLASHBACK_TIME	FLASHBACK_TIME
FULL	FULL
GRANTS	EXCLUDE=GRANT
HELP	HELP
INDEXES	EXCLUDE=INDEX
LOG	LOGFILE
OBJECT_CONSISTENT	A parameter comparable to OBJECT_CONSISTENT is not needed.
OWNER	SCHEMAS
PARFILE	PARFILE
QUERY	QUERY
RECORDLENGTH	A parameter comparable to RECORDLENGTH is not needed because sizing is done automatically.
RESUMABLE	A parameter comparable to RESUMABLE is not needed. This functionality is automatically provided for users who have been granted the EXP_FULL_DATABASE role.
RESUMABLE_NAME	A parameter comparable to RESUMABLE_NAME is not needed. This functionality is automatically provided for users who have been granted the EXP_FULL_DATABASE role.
RESUMABLE_TIMEOUT	A parameter comparable to RESUMABLE_TIMEOUT is not needed. This functionality is automatically provided for users who have been granted the EXP_FULL_DATABASE role.
ROWS=N	CONTENT=METADATA_ONLY
ROWS=Y	CONTENT=ALL
STATISTICS	A parameter comparable to STATISTICS is not needed. Statistics are always saved for tables.
TABLES	TABLES
TABLESPACES	TABLESPACES (Same parameter; slightly different behavior)
TRANSPORT_TABLESPACE	TRANSPORT_TABLESPACES (Same parameter; slightly different behavior)
TRIGGERS	EXCLUDE=TRIGGER
TTS_FULL_CHECK	TRANSPORT_FULL_CHECK
USERID	A parameter comparable to USERID is not needed. This information is supplied as the username and password when you invoke Export.
VOLSIZE	A parameter comparable to VOLSIZE is not needed.
