AVAYA UPG ADV ENGAGE DSG R3 BASE 3YAN

Keep mission-critical Avaya Engage environments upgrade-ready with a 36 Months upgrade subscription tied to the R3 Base license (MPN 337903). This entitlement preserves access to vendor-issued R3 Base release updates and design-level upgrade rights so your infrastructure team can plan scheduled migrations without exposing production services to compatibility gaps. Purchase this upgrade subscription when you need predictable upgrade windows, prioritized Avaya entitlements, and an auditable upgrade path for Engage design components. The SKU is purpose-built for infrastructure and procurement teams that value vendor-backed continuity, predictable lifecycle management and minimized integration effort when adopting R3 fixes or features. Use alongside existing maintenance or preferred support agreements to shorten remediation timelines and retain alignment with Avaya's release cadence.
