As with any applications, the overall emphasis is always to have an automated mechanism for configuration changes to be moved from source to target servers once the testing phase is over. This enables administrators to have an easy and controlled mechanism for setting up higher environments once QA testing on lower environments are completed.
Solution
WebCenter Content has rich API which can be used from Java or Soap frameworks to build on existing solutions or build a command line based automation mechanism for the majority of the functionality.
One of the use cases for this is Configuration Migration Utility (CMU) which is used extensively by WCC administrators to move configurations, views, rules, profiles, metadata, etc., from one server environment to the other.
You can find extensive details on this utility in the Oracle Documentation here: https://docs.oracle.com/middleware/12211/wcc/webcenter-content-admin/GUID-73251F2D-0FAF-4BA6-9F5B-CF8484860758.htm#WCCSA891
During the course of environments being set up for Development, Test, UAT, and finally Production, it is very often needed to move the configurations between the setups. Even though UI is one of the options for accomplishing this, it is much more efficient to have a command line based mechanism.
To achieve this requirement, here we are providing a small Java program, which leverages the Idc Services of CMU along with the relevant additional parameters.

Conclusion
This code sample can be modified per specific requirements and can be run as a one-time operation for moving the entire configuration to a new environment or on an incremental basis, depending on test phases.
It can be run manually or using a cron job on specific intervals as well.
