This appendix describes available ZFS versions, features of each version, and the Oracle Solaris OS that provides the ZFS version and feature.
The following sections are provided in this appendix:
New ZFS pool and file system features are introduced and accessible by using a specific ZFS version that is available in Oracle Solaris releases. You can use the zpool upgrade or zfs upgrade to identify whether a pool or file system is at lower version than the currently running Oracle Solaris release provides. You can also use these commands to upgrade your pool and file system versions.
For information about using the zpool upgrade and zfs upgrade commands, see Upgrading ZFS File Systems and Upgrading ZFS Storage Pools.
