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-Ux release before attempting to migrate from CORE to SCALE.

SCALE Bluefin deprecates and Cobia removes the built-in DDNS, OpenVPN server and client, rsync, S3, and TFTP service. The WebDAV service and share feature are also deprecated in Bluefin and removed in Cobia. New applications are available in Bluefin to serve as replacements for the functions these services provided.

To migrate from CORE to SCALE Cobia, first upgrade to and migrate from the latest CORE release to the latest release of SCALE 22.12 (Bluefin). While running SCALE Bluefin, take the necessary steps to transition from these deprecated services to the applications that replace them, then upgrade to SCALE 23.10 (Cobia). The replacement applications are available in SCALE 22.12 and 23.10.
