Do I have to buy the Cisco-recommended replacement?
No. The bulletin's named successor is Cisco's suggested path, not an obligation. Teams also keep 800 Series units running under third-party maintenance after the support cutoff, migrate to a different vendor, or run low-criticality units to failure with the risk documented. See the support-options guide for the trade-offs.
