Hi, we are currently running a ZD3000 on v 184.108.40.206 build 216. This is part because we still have a number of older ZF7363 APs as well as newer R600s. We are currently looking at upgrading the WiFi in some of our smaller rooms but would be interested in R310s and R610s. However would these newer access points work without issue on this older firmware? Any advice or experience would be gratefully received.
