We have a 3400 controller and we are migrating to a new network infrastructure that is in parallel with the existing one. The new network is using a new subnet for the APs. The controller has connectivity to both the old and new infrastructures to allow for both subnets of APs to be online. We are attempting to move APs one at a time (or switch-by-switch as end users are being migrated). The APs on the new infrastructure/subnet are receiving DHCP addresses from the new scope of the controller, but none of them are checking in as active APs. Only the APs on the old subnet are being reported as active.
Does the 3400 allow for multiple AP subnets? If so, how do I get the APs to register in?
