When you upgrade your system from Pega Platform 8.4 or earlier, you can include the Create stage in your existing case types. By adding the Create stage to your case life cycle, you clearly visualize the views and actions that users interact with before submitting a case. If you choose not to add the Create stage, your application is still fully backward compatible. After the upgrade, your case types work correctly and rely on the pyStartCase starting process. Your case types become independent of the starting process only after you add the Create stage. Adding the Create stage is optional and requires additional configuration, however, the Create stage helps you define your case types and develop your application faster. To fully understand the impact of adding the Create stage to your existing case types, analyze the technical considerations. For more information, see Technical considerations for the Create stage in existing case types.
