Ways to Upgrade a System
When you install a new version of Solaris software on an existing Solaris system, the
installation program lets you choose one of the following options to copy the Solaris
operating environment to disk:
Upgrade – This option merges the new version of the Solaris operating
environment with the existing files on the system’s disks. It saves as many
modifications as possible that you have made to the previous version of the Solaris
operating environment.
Initial – This option overwrites the system’s disk with the new version of the
Solaris operating environment. You must back up any local modifications that you
have made to the previous version of the Solaris operating environment before
you begin the installation and restore the local modifications after the installation
completes.
