Before you install and use Live Upgrade, become familiar with these requirements.
Live Upgrade is included in the Oracle Solaris software. You need to install the Live Upgrade packages on your current OS. The release of the Live Upgrade packages must match the release of the OS you are upgrading to. For example, if your current OS is the Solaris 9 release and you want to upgrade to the Oracle Solaris 10 8/11 release, you need to install the Live Upgrade packages from the Oracle Solaris 10 8/11 release.
Table 3-1 lists releases that are supported by Live Upgrade.
Table 3-1 Supported Oracle Solaris Releases
|
You can install the Live Upgrade packages by using the following:
The pkgadd command. The Live Upgrade packages are SUNWlucfg, SUNWlur, and SUNWluu, and these packages must be installed in that order.
An installer on the Oracle Solaris Operating System DVD, the Oracle Solaris Software - 2 CD, or a network installation image.
Be aware that the following patches might need to be installed for the correct operation of Live Upgrade.

For instructions about installing the Live Upgrade software, see Installing Live Upgrade.
If you have problems with Live Upgrade, you might be missing packages. In the following table, check that your OS has the listed packages , which are required to use Live Upgrade.
For the Oracle Solaris 10 release:
If you install one of the following software groups, these software groups contain all the required Live Upgrade packages.
Entire Oracle Solaris Software Group Plus OEM Support
Entire Oracle Solaris Software Group
Developer Oracle Solaris Software Group
End User Oracle Solaris Software Group
If you install one of these Software Groups, then you might not have all the packages required to use Live Upgrade.
Core System Support Software Group
Reduced Network Support Software Group
For information about software groups, see Disk Space Recommendations for Software Groups in Oracle Solaris 10 8/11 Installation Guide: Planning for Installation and Upgrade.
Table 3-2 Required Packages for Live Upgrade

To check for packages on your system, type the following command.
% pkginfo package_name
Follow general disk space requirements for an upgrade. See Chapter 4, System Requirements, Guidelines, and Upgrade (Planning), in Oracle Solaris 10 8/11 Installation Guide: Planning for Installation and Upgrade.
To estimate the file system size that is needed to create a boot environment, start the creation of a new boot environment. The size is calculated. You can then abort the process.
The disk on the new boot environment must be able to serve as a boot device. Some systems restrict which disks can serve as a boot device. Refer to your system's documentation to determine if any boot restrictions apply.
The disk might need to be prepared before you create the new boot environment. Check that the disk is formatted properly:
Identify slices large enough to hold the file systems to be copied.
Identify file systems that contain directories that you want to share between boot environments rather than copy. If you want a directory to be shared, you need to create a new boot environment with the directory put on its own slice. The directory is then a file system and can be shared with future boot environments. For more information about creating separate file systems for sharing, see Guidelines for Selecting Slices for Shareable File Systems.
Live Upgrade uses Solaris Volume Manager technology to create a boot environment that can contain file systems that are RAID-1 volumes (mirrors). Live Upgrade does not implement the full functionality of Solaris Volume Manager, but does require the following components of Solaris Volume Manager.
