      thx for sugestion

      looks very promising src

      # zfs create pool/project/production
        populate /pool/project/production with data
      # zfs snapshot pool/project/production@today
      # zfs clone pool/project/production@today pool/project/beta
        make changes to /pool/project/beta and test them
      # zfs promote pool/project/beta
      # zfs rename pool/project/production pool/project/legacy
      # zfs rename pool/project/beta pool/project/production
        once the legacy version is no longer needed, it can be destroyed
      # zfs destroy pool/project/legacy
      

      not tested yet
