Solaris 10 What's New

Solaris Live Upgrade 2.1

This feature is new in the Software Express pilot program and in the Solaris 9 8/03 release. This feature is included in the Solaris 10 3/05 release.

Solaris Live Upgrade provides a method of upgrading a system while the system continues to operate. While your current boot environment is running, you can duplicate the boot environment, then upgrade the duplicate. Or, rather than upgrading, you can install a Solaris Flash archive on a boot environment. The original system configuration remains fully functional and unaffected by the upgrade or installation of an archive. When you are ready, you can activate the new boot environment by rebooting the system. If a failure occurs, you have a safety net. You can quickly revert to the original boot environment with a simple reboot. Thus, you eliminate the normal downtime of the test and evaluation process.

New features in Solaris Live Upgrade 2.1 provide the following new functionality.
