AIR-AP1840I-D-K9: Support-exit milestone

AIR-AP1840I-D-K9 keeps the D regulatory-domain letter and K9 controller-based identity in its complete order code. Preserve the D-domain quote, received label and enabled-channel evidence through controller migration.

For D-domain K9 operation, document the controller software owner and end-of-support plan alongside the RF survey. Repeat discovery and client tests after upgrades. As support approaches its final date, preserve a funded migration milestone instead of assuming the controller can maintain this generation indefinitely.

Evidence required before acceptance

For D-K9, assign owners for controller software, remaining support and migration funding. Repeat discovery, radio and representative-client checks after upgrades. Record a dated replacement milestone before April 30, 2027 so continued operation is a controlled decision rather than an accidental dependency.

Procurement decision

Remaining vendor support is finite, so procurement must include a dated exit or replacement decision. Cisco records the 1840 series as end of sale on May 1, 2022 and end of support on April 30, 2027.
