Perform Postupgrade Tasks

This phase is where you set up the environment, configure applications, and test the upgraded system as follows:

• Set Up the Environment. These tasks set up the postupgrade environment, which includes extracting the developers’ databases and running database statistics.

• Application Administration. These tasks set up applications and include such things as setting up user access and visibility of views and screens.

• Application Configuration. These tasks prepare applications for testing, including data migration for specific applications.

• Test the Upgraded System. These tasks test the upgraded system. For development environment upgrades, you perform basic unit tests to verify application function followed by a full suite of regression and stress tests to verify the upgraded system is ready for production.
