Based upon your requirements, you can install Solaris 9 OE using any of the six installation procedures, such as WebStart, Custom JumpStart, Factory JumpStart, Solaris SunInstall, WebStart Flash, and Live Upgrade. WebStart packages all software components as a single entity. Custom JumpStart allows you to customize the Solaris installation. It is specifically useful for mass rollouts. Factory JumpStart does not prompt you for any information. It starts the installation procedure as soon as the installation CDs are inserted in the CD-ROM drive. The WebStart Flash installation provides both GUI and CLI. It helps simultaneously install several systems that use the same software and configuration. The Live Upgrade method is used to upgrade from the previous versions of Solaris to the next.
