Argent has a failover system for their main engines, known as backup engines. The license file is propagated from the main engine to these backup engines.

When a backup engine takes over, there would be no licensing issues, as the backup would have an exact copy of the production license in its local file system.

Argent Defender

The Argent Defender does not have a backup engine. There is no failover support.
