If everything looks OK ( and in my case there were no issues ) proceed with upgrade of zpool and zfs and in case of mirrored boot pool - don't forget to update grub on the second disk.;

Changes since u9 ( zpool v22 , zfs v4 ):

 23  Slim ZIL
 24  System attributes
 25  Improved scrub stats
 26  Improved snapshot deletion performance
 27  Improved snapshot creation performance
 28  Multiple vdev replacements
 29  RAID-Z/mirror hybrid allocator
bash-3.2# zfs upgrade -v
The following filesystem versions are supported:


---  --------------------------------------------------------
 5   System attributes
!!! If system zpool is upgraded to the new version - there will be no way to boot into the old environment !!!

  There are potential issues when upgrading host with multiple zones, see details in the post
