Solaris 10 10/08 Installation Guide: Planning for Installation and Upgrade

Upgrade Programs

You can perform a standard interactive upgrade with the Solaris installation program or an unattended upgrade with the custom JumpStart installation method. Solaris Live Upgrade enables you to upgrade a running system.

Upgrade Program 


For More Information 

Solaris Live Upgrade 

Enables you to create a copy of the currently running system. The copy can be upgraded and then a reboot switches the upgraded copy to become the currently running system. Using Solaris Live Upgrade reduces the downtime that is required to upgrade the Solaris OS. Also, Solaris Live Upgrade can prevent problems with upgrading. An example is the ability to recover from an upgrade if the power fails, because the copy being upgraded is not the currently running system.  

To plan for disk space allocation when using Solaris Live Upgrade, see Solaris Live Upgrade Requirements in Solaris 10 10/08 Installation Guide: Solaris Live Upgrade and Upgrade Planning.

The Solaris installation program  

Guides you through an upgrade with an interactive GUI.

Custom JumpStart program 

Provides an automated upgrade. A profile file and optional preinstallation and postinstallation scripts provide the information required. When creating a custom JumpStart profile for an upgrade, specify install_type upgrade. You must test the custom JumpStart profile against the system's disk configuration and currently installed software before you upgrade. Use the pfinstall -D command on the system that you are upgrading to test the profile. You cannot test an upgrade profile by using a disk configuration file.
