Above are best Oracle database 12c new features. We seen lots of scenarios, very few people and companies are successfully using these kinds of features after upgrading database from prior release. Indeed, every one doesn't require using all of new options. Recently we upgraded 6 biggest data warehousing databases of our UK clients. Still we didn't get any issue after upgrading databases. Stability is Oracle's main feature of every version. Oracle provides all options in new database releases with fixing old bugs, but what about new bugs!! There is no software and RDBMS available without bugs and security black holes.
People are using new SQL characteristics like TRUNCATE TABLE CASCADE option, or execution of SQL query using TOP-N option like FETCH FIRST N ROWS ON. These kinds of options can use in daily database operations and in routine PL/SQL procedures.
Disaster recovery attributes like table level recovery, data file restoration through network are using very rarely because those features are only being used during recovery incident. Online data file movement or table partition management can be used any time. Due to this reason, every attribute or feature doesn't be tested properly after upgrading database.
Some of good new features introduced in Active data Guard and RMAN backup recovery like table level recovery is available in Oracle 12c. You need to test everything before going to plan of upgrade your existing production database. Without testing every application, performance, your backup plans; don't go ahead otherwise you would get some mysterious issues after upgrade your production Oracle server. Better plan create test database server and execute all application with proper data load.
