CBW140AC multiple controller setup separated by VLANs

[GaeMi]

I need to deploy around 100–200 CBW140AC access points at a single site.
Since Cisco’s recommendation is a maximum of 25 APs per controller, I’m considering dividing the deployment into multiple controller domains, each separated by different VLANs.

Can I operate multiple CBW140AC controllers on the same site if they are separated by VLANs?

I’d also like to know if this type of separation is possible with Mobility Express and EWC.

maximum of 25 APs per controller

what controller is this, as per i know if you have WLC controller airos or cat controller i do not see this limitation.

or you installing CBW as controller here ?

Yes. I will install CBW as controller.

The CBW maximum AP numbers are 50 AP, but recommendation is 25 AP.

I just want to know if I divide the VLANs on my switch, I could
operate the multiple AP controllers on my switch.

Because we can't provide other type of AP controller now on that
network anymore.
