ENS 10.1 is supported on Windows Server 2008 and newer (see https://kc.mcafee.com/corporate/index?page=content&id=KB82761#Servers). I don't know any official announcement, but I think McAfee is moving all Windows/Linux Products into the Endpoint Security Platform.
When we migrated to ENS 10 from SCEP we were told that ENS works fine on server OS as well. Currently we use ESET on our Servers and looked at Move but that was not the way our server team wanted to go. Curerntly we still have ESET but we have plans to migrate to ENS in the future
