This procedure only applies to TrueNAS Enterprise (HA) systems. If attempting to migrate from FreeBSD- to Linux-based TrueNAS versions, see TrueNAS Migrations.
If the system does not have an administrative user account, create the admin user as part of this procedure.
Installing TrueNAS on High Availability (HA) systems is complicated and should be guided by Enterprise-level support. Contact TrueNAS Enterprise Support for assistance whenever attempting to install TrueNAS on Enterprise HA hardware.
Contacting Support
Customers who purchase TrueNAS hardware or that want additional support must have a support contract to use TrueNAS Support Services. The TrueNAS Community forums provides free support for users without a TrueNAS Support contract.
Enterprise Migrations
TrueNAS Enterprise customers with High Availability (HA) or Non-HA TrueNAS Hardware should consult with TrueNAS Enterprise Support for assistance before attempting to migrate.

- An extended maintenance window.
- Executing the migration process in a precise order.
- Additional system configuration to update network interfaces and add new administrator accounts.
