Solaris Live Upgrade System Requirements

• You can upgrade from the Solaris 2.6, Solaris 7, or Solaris 8 operating environment to the Solaris 8 or Solaris 9 operating environment.

• You cannot upgrade to the Solaris 7 operating environment.

• You must upgrade to the same release that contained the Solaris Live Upgrade software that you installed on the currently running system. For example, if on your current operating environment you installed Solaris Live Upgrade from the Solaris 9 release, you must upgrade to the Solaris 9 release.

Solaris Live Upgrade is included in the Solaris 9 software, but if you want to upgrade from previous releases, you need to install the Solaris Live Upgrade packages on your current operating environment. You can install the Solaris Live Upgrade packages from the following:

• An installer on the Solaris 9 DVD, the Solaris 9 Software 2 of 2 CD, or a net installation image.

• The pkgadd command. If you are using the pkgadd command, the packages are SUNWlur and SUNWluu, and they should be installed in that order.
