Solaris 9 12/03 Installation Guide

Upgrading (Overview)

An upgrade merges the new version of the Solaris operating environment with the existing files on the system's disk. An upgrade saves as many modifications as possible that you have made to the previous version of the Solaris operating environment.

You can upgrade any system that is running the Solaris 2.6, Solaris 7, or Solaris 8. Type the following command to see the version of Solaris software that is running on your system:

$ uname -a

You can upgrade the Solaris operating environment by using the following installation methods.

Note –

Use the smosservice patch to upgrade diskless clients. For detailed instructions, refer to System Administration Guide: Basic Administration or to smosservice(1M).

If you are already running the Solaris 9 operating environment and have installed individual patches, upgrading to a Solaris 9 Update release causes the following:

Any patches that were supplied as part of the Solaris 9 Update release are reapplied to your system. You cannot back out these patches.
Any patches that were previously installed on your system and are not included in the Solaris 9 Update release are removed.

You can use the Patch Analyzer to determine which patches, if any, will be removed by upgrading to the Solaris 9 Update release. For detailed instructions about using the Patch Analyzer, refer to Upgrading to a Solaris Update Release.

You cannot upgrade your system to a software group that is not installed on the system.

However, during the upgrade you can add software to the system that is not part of the currently installed software group.
