Migrate existing Encryption Key to Oracle 12c
We had created Encryption Key back in 11g using "ALTER SYSTEM SET ENCRYPTION KEY" and upgraded the database to 12c. Now we would like to change the existing Encryption Key.
Going through the documents, it looks like We would need to move the key initially to Keystore and then change the key in Keystore.
What procedure should I need to follow to accomplish this task. Any documents related to this would be helpful.
