Hello, how I can comfortably and quickly switch my WI-FI controller from Mobility Express (Cisco Aironet 1815) to WLC based on Cisco Catalyst 9117AXI, in network 44AP. Thanks 

I have a controller 9800 (firmware 17.3..5) with more than 200 points, and there was a need for a few more points, I bought it - C9117AXI-EWC-E V01 with a controller (configured as a point). When you connect them to the controller, they work normally...
