Note - Separate Release Notes with instructions for upgrading platform software and firmware are also published at the web site where this document is published. Although it is recommended that you upgrade directly to the latest software release available, more than one version of the Release Notes might be available, to provide the ability to return to earlier releases for troubleshooting.

Note - The software on the CDs that are shipped with the system is the latest available at the time of shipping and can be used for reinstallation or system recovery. Because software versions are updated frequently, check the product download site for the latest versions of the software that are qualified by Sun.
