Migrating from CORE

  2 minute read.

On March 20, 2024, iXsystems announced that the FreeBSD-based TrueNAS CORE platform has entered “sustaining engineering phase within the TrueNAS project.” With this transition, TrueNAS 13.0 and 13.3 continue to receive bug fixes related to stability and security. New feature development and component improvement continues on Linux-based TrueNAS versions.

Existing TrueNAS 13.0 and 13.3 users who are comfortable with their TrueNAS system can remain on that major version. Users looking for new feature development can sidegrade to the Linux-based TrueNAS platform at any time, preserving data and essential NAS functionality.

TrueNAS users wanting to migrate from the latest FreeBSD-based 13.0-U6 or 13.3 CORE release to the Linux-based TrueNAS version 24.10 or later can migrate to 24.04 and earlier using the UI, but must clean install if migrating to later releases. Attempting to migrate directly to 24.10 or later releases using the UI is not supported.

Download a copy of the iso for the latest maintenance release of 24.10 or later, then follow the migration instructions in this Getting Started section of the TrueNAS Documentation Hub to move from the FreeBSD-based to the Linux-based version of TrueNAS.
