Not sure what you mean with update. If you want to upgrade a machine from e.g. Solaris 9 to Solaris 10, take a look at the Release and Installation Collection on docs.sun.com. It will explain the various options (re-install, upgrade, live upgrade). If you're talking about installing patches to update a certain release of Solaris to its most current state, read about dealing with Solaris Patches in the Basic Administration guide on docs.sun.com and check out http://sunsolve.sun.com/ Especially as you have servers with different releases of Solaris, I recommend taking a look at http://www.par.univie.ac.at/solaris/pca/ Unlike Sun's own patch tools, it works on any release of Solaris, is much simpler to use for novice users, and more versatile for advanced admins. mp.
