There is also a new R-Series product line that can run CORE, Enterprise, and SCALE editions of TrueNAS. All of these can be updated via the web UI and include graphical enclosure management.

For those with FreeNAS installed on your system, we recommend upgrading to FreeNAS 11.3-U5 first and then upgrading to TrueNAS 12.0-U5 with a single click to retain roll-back options. While it is an easy web update, we do recommend waiting to update your system’s zpool feature flags until you are finished validating your performance and functionality.
