Tracer SC will be considered end-of-life on December 31, 2022. Trane recommends identifying a migration plan for replacing the Tracer SC controller with the next-generation Tracer SC+ controller. Tracer SC+ can function as a drop-in replacement for Tracer SC, providing significant updates to security capabilities.\n\nTrane has identified the following specific mitigations:\n\nTracer SC: Upgrade to v4.4 SP7 or later\nTracer SC+: Upgrade to v5.5 SP3 or later\nTracer Concierge: Upgrade to v5.5 SP3 or later"
