The Solaris 10 10/09 release provides the ability to install a ZFS root file system and configure a zone root on ZFS. Typically, you can create and configure a zone root on ZFS as you wish. If you plan to use Solaris Live Upgrade with ZFS and zone configurations, review the following information:
If you want to use Solaris Live Upgrade with zone configurations that are supported in the Solaris 10 10/09 release, you will need to first upgrade your system to the Solaris 10 10/09 release by using the standard upgrade program.
Then, with Solaris Live Upgrade, you can either migrate your UFS root file system with zone roots to a ZFS root file system or you can upgrade or patch your ZFS root file system and zone roots.
You cannot migrate unsupported zone configurations from a previous Solaris 10 release directly to the Solaris 10 10/09 release.
For a detailed description of supported zone configurations to be upgraded or patched in the Solaris 10 10/09 release, see Migrating a UFS Root File System to a ZFS Root File System (Solaris Live Upgrade) in Solaris ZFS Administration Guide.
For complete instructions on setting up these configurations, see Solaris Installation and Solaris Live Upgrade Requirements for ZFS Support in Solaris ZFS Administration Guide.
Review the information in this chapter before you begin your migration to a ZFS root file system or before setting up zones on a system with a ZFS root file system. Follow the recommended procedure exactly to set up zones on a system with ZFS root file system to ensure that you can use Solaris Live Upgrade on that system.
