The article explains how to upgrade the pool, but sometimes also the filesystems need upgrade (and some of them might need to be upgraded in single-user to avoid being in-use).
% zfs upgrade
This system is currently running ZFS filesystem version 3.
The following filesystems are out of date, and can be upgraded. After being
upgraded, these filesystems (and any 'zfs send' streams generated from
subsequent snapshots) will no longer be accessible by older software versions.
VER FILESYSTEM
--- ------------
1 z
% zfs upgrade -v
The following filesystem versions are supported:
VER DESCRIPTION
--- --------------------------------------------------------
1 Initial ZFS filesystem version
2 Enhanced directory entries
3 Case insensitive and File system unique identifer (FUID)
For more information on a particular version, including supported releases, see:

Where 'N' is the version number.
