Explanation
On Catalyst 9800-series controllers, you use the wireless mobility mac-address command to add an AireOS WLC as a mobility peer by its system MAC address. This ensures that APs can discover and associate with the new 9800 WLC and that client session context is exchanged for seamless roaming between the legacy and new controllers, even across an SSO failover.
