Upgrading the SDL Tridion 2013 SP1 HR1 UGC Moderation Web service
Before SDL Web 8, the UGC Moderation Web service (now called the UGC Moderation service) could only exist as (part of) a Web application. As of SDL Web 8, it can also be a standalone microservice. How you upgrade the Role depends on how you have it installed now: as a Java/JSP Web application or as a .NET Web application.
