Cisco BAC 4.0 Upgrade License for 500,000 Subs | Enterprise Licensing — BAC-4.0UPGSVS500K=

Scale BAC 4.0 to support 500,000 subscribers without replacing the underlying platform. This Cisco upgrade license is built for organizations that need to extend capacity in a predictable way, preserving the investment already made in the current deployment while aligning entitlement to a larger subscriber base. For service providers and enterprise teams managing growth, the value is in continuity. Rather than introducing a new system or re-architecting the environment, this license updates the software entitlement to match expanded demand. That makes planning simpler, procurement cleaner, and operational risk lower. It is a practical fit for environments where subscriber counts are rising and service assurance matters. By moving to the 500,000-subscriber tier, teams can keep the platform aligned with current scale requirements and avoid the friction of piecemeal capacity workarounds. The result is a more controlled path to expansion, backed by Cisco licensing.
