Is it possible to run different versions in a master local setup? 6.4.x on the Master and 6.3.1.8 on one of the locals. I have to support old ap-65 and 70’s on the old end and IAP-275’s (converted to managed by Mobility Controller) on the newer end, all using the same SSID’s. According to the docs, IAP-275 will only work with AOS 6.4 and higher and that AOS doesn’t not support 65’s and 70’s.
