In Avaya IX™ Messaging High Availability installations, TLS configurations must be applied to both the primary server and all secondary servers. This ensures that communication with the PBX(s) is secured across all servers that are part of the high availability setup. The application of TLS configurations across all these servers is crucial for maintaining the integrity and security of the messaging system.

References: The answer is based on the standard practices for securing communications in high availability installations, which typically involve applying TLS configurations to all servers within the environment to ensure consistent security measures are enforced1.
