|Oracle Solaris 10 1/13 Installation Guide: Live Upgrade and Upgrade Planning Oracle Solaris 10 1/13 Information Library|
You can use Live Upgrade to add patches and packages to a system. When you use Live Upgrade, the only downtime the system incurs is that of a reboot. You can add patches and packages to a new boot environment with the luupgrade command. When you use luupgrade command, you can also use a flash archive to install patches or packages.
Caution - When upgrading and adding and removing packages or patches, Live Upgrade requires packages or patches that comply with the SVR4 advanced packaging guidelines. While Oracle packages conform to these guidelines, Oracle cannot guarantee the conformance of packages from third-party vendors. If a package violates these guidelines, the package can cause the package-addition software during an upgrade to fail or alter the active boot environment.
For more information about packaging requirements, see Appendix C, Additional SVR4 Packaging Requirements (Reference).
