What are the requirements to serve El Capitan updates?
I know OS X Server 5 is now OS independent, but do I need to upgrade the server to El Capitan as well to serve 10.11 updates? We are currently running OS X 10.10.x with Server 4 and I don't know if I need to upgrade both or just Server.
I see nothing in the documentation about this specifically.
Mac mini, OS X Server, Server app 3.2.1
