|Oracle Solaris 10 1/13 Installation Guide: Live Upgrade and Upgrade Planning Oracle Solaris 10 1/13 Information Library|
If you have a UFS file system, Live Upgrade works the same as in previous releases. You can now migrate from UFS file systems to a ZFS root pool and create new boot environments within a ZFS root pool. For these tasks, the lucreate command has been enhanced with the -p option. The lucreate command has the following syntax:
# lucreate [-c active-BE-name] -n BE-name [-p zfs-root-pool [-D /var]]
The -p option specifies the ZFS pool in which a new boot environment resides. This option can be omitted if the source and target boot environments are within the same pool.
The lucreate command -m option is not supported with ZFS. Other lucreate command options work as usual, with some exceptions. For limitations, see System Requirements and Limitations When Using Live Upgrade.
For ZFS information, including overview, planning, and step-by-step instructions, see Oracle Solaris ZFS Administration Guide
