Solaris Live Upgrade is a feature introduced in Solaris 9 OE. This feature enables you to upgrade to a newer release of Solaris OE. However, if you use a previous version of Solaris OE, such as Solaris 2.6 or Solaris 7 or 8, then you would be required to install Solaris Live Upgrade packages on your current operating system. You can install the Solaris Live Upgrade packages from the Solaris 9 DVD or Solaris 9 Software 2 of 2 CD.
When upgrading from Solaris 2.6 to Solaris 9, you can use the WebStart, SunInstall, and the JumpStart upgrade methodologies. For Solaris 7 and 8, you can use Live Upgrade to upgrade, in addition to WebStart, SunInstall, and JumpStart.
Disk Space Requirements
Live Upgrade requires you to create a boot environment on your system. Each boot environment may require a minimum of 350Mb to a maximum of 800Mb of disk space, depending on your system software requirements.
You need to estimate the size of the file system to create the boot environment. To do so, start the process of creating a new boot environment. The process automatically calculates the size of the file system. When you find the size, terminate the process.
To create a boot environment, all you need is a disk that can serve as a boot device.
If you are upgrading from Solaris 2.6, you require the following packages:
Use the following packages if you are upgrading from Solaris 7:
If upgrading from Solaris 8, use the following packages:
