How to Migrate a UFS Root File System With a Zone
Root to a ZFS Root File System (at Least Solaris 10 5/09)
Use this procedure to migrate a system with a UFS root file system and a zone root to at least the Solaris 10 5/09 release. Then, use Oracle Solaris Live Upgrade to create a ZFS BE.
In the steps that follow, the example UFS BE name is c0t1d0s0, the UFS zone root is zonepool/zfszone, and the ZFS root BE is zfsBE.
-
Upgrade the system to at least the Solaris 10 5/09 release if it is running a previous Solaris 10 release.
For information about upgrading a system that is running the Solaris 10 release, see Oracle Solaris 10 9/10 Installation Guide: Solaris Live Upgrade and Upgrade Planning.
-
Create the root pool.
For information about the root pool requirements, see Oracle Solaris Installation and Oracle Solaris Live Upgrade Requirements for ZFS Support.
-
Confirm that the zones from the UFS environment are booted.
# zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / native shared 2 zfszone running /zonepool/zones native shared
-
Create the new ZFS boot environment.
# lucreate -c c1t1d0s0 -n zfsBE -p rpool
This command establishes datasets in the root pool for the new boot environment and copies the current boot environment (including the zones) to those datasets.
-
Activate the new ZFS boot environment.

-
Reboot the system.
# init 6
-
Confirm that the ZFS file systems and zones are created in the new BE.

Example 5–7 Migrating a UFS Root File System With a Zone Root to a ZFS Root File System
In this example, a Oracle Solaris 10 9/10 system with a UFS root file system and a zone root (/uzone/ufszone), as well as a ZFS non-root pool (pool) and a zone root (/pool/zfszone), is migrated to a ZFS root file system. Ensure that the ZFS root pool is created and that the zones are installed and booted before attempting the migration.
