Easy question here. Hopefully. I'm upgrading my WLC and ISE implementations. ISE 3.1 is now the recommended version, but if I look at the compatibility matrix, and a couple other places, it shows that WLC version 17.3.5 is compatible with ISE 3.1, but every version after that is only compatibly with 3.0. Is this a documentation error? Or can I not advance beyond 17.3.5b?
