Before starting with the RCU I wanted to share that Discoverer 11.1.1.4.0 is the latest supported version. In the future a new version will be available and so RCU utility has to be download accordingly.
The DISCOVERER5 schema in 10g AS will be replaced with a new schema , but the PORTAL schema will not have any change and the same schema will be used.
After installing the RCU you should see TST_DISCOVERER schema in the database.
