AP 9120 AX as Standby Controller

[doverture]

Good Morning, a customer is deploying a campus solution completely Cisco based.

For the wireless part, they bought just one C9800-L-F controller and more o less 25  9120 AX controller integrated APs.

They ask me a possible solution with one of the APs as secondary (standby) controller with the C9800 as primary: is this a valid and

reliable setup?

Any suggestion is appreciated!

Thanks in advance

  - I don't recommend it because the EWC solution is being phased out :  https://www.cisco.com/c/en/us/products/collateral/wireless/embedded-wireless-controller-catalyst-access-points/wireless-ewc-access-point-eol.html
    Of course you would only be able to do N+1 High Availability and no HA-SSO , but because of functional differences (EWC restrictions) compared to a real wireless controller even N+1 would break for certain functions, so it becomes a no go,
