The ZFS Administration Guide describes how to do this in the section on Migrating a UFS Root File System to a ZFS Root File System (Solaris Live Upgrade). LiveUpgrade only applies to SXCE, though. The OpenSolaris installer does not currently have the ability to do such things. http://www.opensolaris.org/os/community/zfs/docs/zfsadmin.pdf -- richard
