We have a number of IAP-92/93 AP's that are used for Barcode Scanners so the traffic is very light, we want to add some more AP's (IAP-207) to cover the offices for general access, we want to retain the existing VC and AP's for now and will replace them over time, I'm not sure about the firmware compatability between them though, the exsiting VC is running 6.4.2.6-4.1.3.0 which seems to be the latest for it, would the IAP-207 work with it???
