Because the physical ports don't match, the port trust is removed by default, and needs to be re-enabled. In
the example below, the Trusted column shows that the port trust is disabled for all ports.

Use the interface range command to re-apply port trust to all of the gigabit Ethernet ports on the controller.
Then issue the show port status command to verify port trust has been restored.
(host) (config) #interface range gigabitethernet <slot>/<module-start>/<port-start>-<module-
end>/<port-end>
(host) (config-range) #trusted

Save your Configuration
Now, you must save the configuration settings on the new controller. Issue the write memory command in
the command-line interface, or click the Configuration tab and select the Save Configuration button at the
top of the WebUI page.
(host) (config) #write memory)
Remove the Existing Controller
If you are only replacing a backup controller, remove the existing backup controller, then connect the
replacement controller to the network. If you are replacing both an active controller and a backup controller,
replace the backup controller first.
When the active master controller is removed from the network, the backup master immediately assumes the
role of active master, and all active APs associate to the new active master controller within a few seconds.
Therefore, when you add another controller to the network, it will, by default, assume the role of a backup
controller.
If you changed the VRRP priorities of your redundant master controllers prior to replacing the primary master
controller, you may wish to change them back once the new primary master is active on the network.
