For versions of Oracle 11g R2, Oracle Recovery Manager (RMAN) replicates a database to a different Oracle home and opens it with NORESET LOGS option. From Oracle 12cR1, database RMAN introduced an option called ‘NO OPEN’, which duplicates your database to a new location and keeps it in an unopened state. Using this feature we can duplicate a database to more recent target database version, allowing us to update our existing database to the most recent version.
