Avaya UPG ADV CMS R18 IEX HIST 1YPP

Maintain continuity for Avaya CMS R18 IEX deployments with a 1-year historical support entitlement designed for upgrade and service alignment. This offering is intended for organizations that need to keep an installed CMS environment covered while preserving the support relationship associated with the platform. For infrastructure teams, the value is operational clarity. Instead of leaving a legacy or in-place deployment exposed, this entitlement helps formalize coverage for the current release path and supports planning around maintenance windows, lifecycle decisions, and budget control. It is a practical fit for environments where contact center reporting, call management, or related CMS functions remain part of the operational stack. Because this is a support and warranty item rather than a hardware or software feature set, the emphasis is on entitlement continuity, not new functionality. That makes it a better fit than ad hoc support arrangements when the goal is to keep the environment governed, documented, and easier to manage through the next planning cycle.
