ORA-39358: Export dump file version 12.1.0.2.0 not compatible with target version 11.2.0.4.0

PROBLEM:
While importing dump file, got error as

ORA-39358: Export dump file version 12.1.0.2.0 not compatible with target version 11.2.0.4.0 .

SOLUTION:
1. Check the compatible parameter of both source and target database.

SOURCE DB:
SQL>show parameter compatible

NAME TYPE VALUE
------------------------------------ ----------- ---------
compatible string 12.1.0.2.0
noncdb_compatible boolean FALSE

TARGET DB:

SQL> show parameter compatible

NAME                                 TYPE        VALUE
------------------------------------ ----------- --------
compatible                           string      11.2.0.4.0

We can see the source compatible parameter is higher version(12.1.0.2) and target is lower(11.2.0.4). A dump file generated from database with higher compatible parameter can’t be imported to a database with lower compatible value. Either both should be same or target db compatible can be higher than the source compatible.

To fix it, While taking export use VERSION=11.2 parameter 

expdp dumpfile=test.dmp logfile=test.log directory=EXPDIR full=y version=11.2

Now try to import this, It will succeed without any issues.
