The upgrade from Raspbian Jessie to Raspbian 9 Stretch is a relatively simple procedure. However, exercise caution, as there is always a chance to break the entire system. The fewer installed 3rd-party packages and services, the more likely you are able successfully to upgrade your Raspbian Linux system.
