Upgrading Overview

You can upgrade the Sun Cluster Geographic Edition software on a running cluster without disruption. Because the Sun Cluster Geographic Edition software installation process does not require you to restart the Sun Cluster software, the cluster remains in production with services running. You can also use the upgrade process to install a Sun Cluster Geographic Edition patch without downtime. Sun Cluster Geographic Edition software configuration data is retained across the upgrade process.

Ensure that you have installed all the required patches for your cluster configuration on each node of every cluster before you start upgrading the software.

See Required Patches in Sun Cluster Geographic Edition 3.1 2006Q4 Release Notes for the location of patches and installation instructions.

The Sun Cluster Geographic Edition software must be upgraded on all nodes of all clusters that have a partnership with the cluster you are upgrading.

If you want to upgrade the Solaris OS during the Sun Cluster Geographic Edition software upgrade process, you must remove the Sun Cluster Geographic Edition packages before you upgrade the Solaris OS.
