Applications upgrade lifecycle
You can use three environments to complete the upgrade process: your current production environment, a new development environment, and a new test environment. You will duplicate your production environment to create the development and test environments. Run the out-of-box upgrade and create the custom upgrade on the development environment, and then run and test the custom upgrade on the test environment before you apply it to your production environment. The figure below provides an overview of the steps in the upgrade process.
The following flow chart illustrates the lifecycle of a typical upgrade of Service Manager applications.
