We are a large consumer with Catalyst Center.
We are doing SDA-Access and SDA-Wireless. We also have Meraki Cloud from some small wireless stuff we did are remote sites.
As someone already mentioned i dont think either platform can be the manager of the other.
i think you will have to make a fundamental choice to use MD or CC for network management.
we currently are using 9300/9500 catalyst switches.
we currently have two HA paired 9800 Wireless controllers.
we are using 4800 Series Catalyst APs and also have 9120s.
we are using EWLC controller deployments when we do wireless at FIAB (Fabric in a Box) deployments with Catalyst Center.
Our paired 9800s only manage the APs for our Main Campus Fabric.
