We currently have an Unleashed network on 200.7.
However, R500's (end of support: 2024) do not support 200.8 or later. Adding a 200.8 device to the network caused severe issues (R500's on 200.7 started rebooting).
We have quite a few, and they are not old devices, so we do not feel it is warranted to replace these yet.
I would like to know if ZoneDirector supports APs on different firmware versions.
Reasoning: I assume that R500 firmware will stop being updated at some point and would not want these to become paperweights.
I am aware that vSZ does, per this article: https://support.ruckuswireless.com/articles/000004826
but could not find the same article for ZD.
