Restore .bkp file of different version oracle I have 12.1 Oracle version .bkp file. Can I restore it in 11.2 Oracle XE?
I have used below command:

 RMAN&gt; restore controlfile from
2&gt; '/home/db_dump/201101.BKP'; 


And now getting below error:

ORA-19690: backup piece release 12.1.0.0.0 incompatible with Oracle release 11.2.0.2.0


Please help me to figure out this or give some conclusion.
No, you can't restore 12c backup in 11g environment. 

If you need to copy data, then restore backup with 12c version and use expdp to export. After that import data to 11g.
