Thanks Sean. I've been going through the admin guide but it doesn't seem to cover migration at all, and since it's a different OS I was worried that wouldn't be an option.
Can anyone share an upgrade story? I'm wondering if it makes more sense to simple put the setup SZ 100's on the same IP's as the ZD's currently are and just reboot all the AP's, then they will auto connect, replace their firmware and should work, or it I should migrate to the new controller son new IP addresses.
I'm' also curious about how failover of the controllers work, the SZ 100's run an active/active cluster as far as I've read, does that mean a forced failover event results in no loss of connection on the clients?
