Scheduling an outage for your Identity Manager application
Scheduling database administrator support
Notifying users before taking the application offline
Shutting down specific resources, processes, or applications that are used only in your Production environment
Upgrading your Production environment might also pose special considerations that require advanced techniques. For example, to minimize the downtime of your Identity Manager application, you might want to upgrade a separate server and a separate database in a parallel Production instance. After upgrading the parallel instance, you might want to make the original Production instance unavailable, synchronize from the actual Production system to the parallel instance any data that changed during the time that the parallel instance was being upgraded, and then switch over to the parallel Production instance.
Advanced techniques such as these are beyond the scope of this document. If you have any special considerations or technical questions related to upgrading your Production environment, contact your Sun Professional Services to request assistance.
