oracle database error during DB startup

Issue:
I have faced some issue  & DB did not open when I restart the database using Pfile  and got the below error.

SQL> startup pfile='initORA1.ora' mount;
ORACLE instance started.

ORA-00201: control file version 11.2.0.4.0 incompatible with ORACLE version
11.1.0.0.0
ORA-00202: control file: '/appdb1/oradata/oradb1.redoctrl01/control01.ctl'

Cause:
looks like the compatible  parameter value different in P & SP file

Solution:
corrected the Pfile according to SP file compatible value  and restarted the database and it opened without any issues.
