Due to the slow buying procedure, we still have AP 61 wich are blocked on 6.3 AOS and also have AP 205 wich support AOS > 6.3 only.
Because of this we have 2 controllers with different AOS version.
We keep them on same layer 2 Vlan since we need users to roam
between controller.
Maybe that's not the perfect strategy so any advice on this point is warmly accepted.
