Data Pump OR Export Compatibility Version chart used for downgrade the EXPDP / EXP backup
EXPDP / EXP is used for logical database backup, it will used to export and import the database backup on different server or refresh them. It is very powerful utility in Oracle.

Then i need to take EXP backup with version Parameter mention value to 10.2 for downgrade the backup.
