Avaya PASS Plus Upgrds SW Spt-SLNAQU

Keep production Avaya systems eligible for vendor updates and technical remediation with the PASS Plus upgrade support entitlement. Purchased as a service add-on, this SKU restores or extends upgrade rights so your Avaya software can receive packaging-level fixes, firmware updates where applicable, and official release access. For infrastructure teams operating critical telephony and collaboration stacks, PASS Plus removes procurement friction when applying vendor-released fixes during maintenance windows. This support entitlement is designed for predictable software lifecycle management: it restores upgrade privileges to match installed licenses, maps to Avaya's published releases, and provides a single point of entitlement for renewals. Use PASS Plus when consolidating license estates, preparing for a major upgrade, or ensuring compliance ahead of audit cycles. The offering complements on-site maintenance and third-party monitoring by preserving direct vendor software delivery and official release notes — essential when diagnosing release-specific behaviors or applying vendor-recommended mitigations.
