TrueNAS Enterprise customers should consult with iXsystems Support before attempting migrate to TrueNAS SCALE.
The process requires:
Backing up critical data. An extended maintenance window. Executing the migration process in a precise order. Additional system configuration to update network interfaces and add new administrator accounts. Review the Migration Preparation article to see detailed notes and caveats about the migration process.

TrueNAS SCALE incorporates all the major TrueNAS CORE storage and sharing features with a web interface based on Debian GNU/Linux. Because SCALE shares the same UI as the FreeBSD-based TrueNAS CORE, users might notice there are similarities. However, SCALE does incorporate some differences, primarily in component naming.
Disks TrueNAS Core utilizes a numerical listing of drives in a system.
TrueNAS SCALE uses a lettered format for drive identification.
SCALE still labels NVMe drives with a numeric value.
This section provides information and instructions for TrueNAS CORE users wanting to migrate to SCALE.
Migrating TrueNAS from CORE to SCALE is a one-way operation. Attempting to activate or roll back to a CORE boot environment can break the system.
Upgrade your CORE system to the latest publicly-available 13.0-U6.1 (or later) release before attempting to migrate from CORE to SCALE.
Linux treats device names differently than FreeBSD so please read Component Naming for more information.
Early testers of TrueNAS SCALE are advised:
On June 29, 2021, a new feature was merged into the TrueNAS fork of OpenZFS[1] for developers to test and integrate with other parts of the system. This feature included a new pool feature flag to signify an on-disk format change to how xattr names are encoded on Linux. This original version of the feature was easily activated by a default pool configuration. We quickly decided that the default configuration should not activate this feature until it is available in upstream OpenZFS, and on July 15 we merged changes[2] which make the defaults prevent activation of the new feature.
Users of TrueNAS SCALE 24.04 (Dragonfish) or newer can migrate data from a third-party NAS solution onto TrueNAS SCALE using the Syncthing Enterprise application. The Syncthing Enterprise application can mount remote SMB shares in a manner that preserves relevant metadata. TrueNAS SCALE 24.10 (Electric Eel) also adds migration support for SMB alternate data streams (ADS), used to store application-specific metadata.
Syncthing Overview Syncthing is a file synchronization application that provides a simple and secure environment for file sharing between different devices and locations.
