We have a SP2016 (16.0.4327.1000 build, Release candidate) installed. I checked there is no Distrubuted Cache service setup. So I set it up on 2 WFE server. After that I change the role of WFE servers to "Custom". I found nothing have changed but I am not sure. All services on WFE have same status before conversion.
May I know what is "Role conversion" actually perform beside change the naming?
P.S. by some project restriction I cannot patch the farm at this moment.
