Upgrading to Solaris Cluster 3.2 1/09

Solaris Cluster provides several different upgrade paths to version 3.2 1/09:

• Standard upgrade

• Dual-partition upgrade

• Live upgrade

• Rolling upgrade

Several factors determine which paths are available to a given deployment of Solaris Cluster:

• The current operating system version: Solaris 8, Solaris 9, or Solaris 10

• The processor architecture: SPARC or x86

• The current version of Solaris Cluster: 3.0 through 3.2

• Whether a concurrent operating system upgrade is planned

The Sun Cluster Upgrade Guide for Solaris OS describes which paths are available in each context, provides guidance in choosing the most appropriate path, and gives detailed instructions for performing the tasks associated with each upgrade path. Additionally, the Solaris Cluster 3.2 1/09 Release Notes provide information about issues related to upgrading to Solaris Cluster 3.2 1/09.

Solaris Cluster does not support direct upgrade on x86 based systems running Solaris 8 or Solaris 9. See the Sun Cluster Upgrade Guide for Solaris OS for the best approach to upgrading in this situation.
