Installing Solaris Live Upgrade

You need to install the Solaris Live Upgrade packages on your current OS. The release of the Solaris Live Upgrade packages must match the release of the OS you are upgrading to. For example, if your current OS is the Solaris 9 release and you want to upgrade to the Solaris Express 5/07 release, you need to install the Solaris Live Upgrade packages from the Solaris Express 5/07 release.

Installing Solaris Live Upgrade involves either installing by using the pkgadd command or by using the installer.
