SAP suggests that you install and use a test or development server, then remove it before you create the production server.
Using a test server makes it easier to plan and test different configurations and less stressful to recover from mistakes. It is much easier to learn how to install and administer new features when there is no risk of having to restart a production server or re-create a production database.
SAP suggests that you use a test server from installation or upgrade through configuration. It is in these initial steps that you make some of the most important decisions about your final production system.
