Re: ORA-00201: controlfile version 8.0.0.0.0 incompatible with ORACLE version 9.2.0.0.0

Hi Rahul,

"ORA-00201: controlfile version 8.0.0.0.0 incompatible with ORACLE version 9.2.0.0.0"

Have you tried / checked to mount the database by adding compatibility parameter under pfile to regenerate the spfile ?
