Benefits of a baseline for control and recovery
When you think about the task of implementing ongoing changes, you realize that you would like to set up a way to automate the synchronization of versions of the application across multiple subsystems.
Knowing that it is impossible to anticipate every consequence of performing a change, you also see that you might need to fall back to a previous version of the application in the future.
Establishing a baseline provides a way to create a point of recovery. By taking baselines of each version of the application, you can perform a comparison between two versions of an application. The CDL that is generated during this process can then be applied to each receiving subsystem. You can use this strategy to apply upgrades to applications running on other subsystems without running the risk of losing any local modifications.
