Avaya 291368J SA ESS C/D Core R6 to Mainstream 5YPP

Protect your Avaya environment during the transition from C/D Core R6 to mainstream support with a 5-year essential support package. Built for teams that need a clear maintenance path, this coverage helps preserve operational continuity while you plan upgrades, align refresh cycles, and manage risk across the installed base. For infrastructure leaders, the value is predictability. Instead of reacting to end-of-support pressure, you get a defined support window that supports longer planning horizons and more disciplined procurement decisions. That matters when the platform still carries business-critical traffic and replacement timing must align with budget, staffing, and change windows. This support offering is suited to organizations that want to extend the useful life of existing Avaya deployments without losing vendor-backed coverage. It helps reduce uncertainty during migration planning and gives procurement teams a cleaner way to bridge from legacy support status to mainstream lifecycle management.
