I realize the UNMS is the future. I am recommending Ubiquiti to a customer with 9 locations to upgrade as a part of our installation.
I havent used UNMS, just Unifi, and I am not sure if I can safely recommend they purchase ER-X units and install a UNMS server today, or if it still has quirks. In case of the latter I could just tell them to get the USG units and install a Unifi controller.
Just looking for some feedback as to what would best suit a production environment today. Particularly from @JaredBusch if he's around.
