We just released ServiceControl 6.0.0 that uses RavenDB 6.2.
@janv8000 and everyone else, this version also officially supports configuring your container to connect to an externally provided RavenDB server. However, to ensure compatibility between the client in ServiceControl and the server we do check to make sure you are connecting to a RavenDB server version greater than or equal to 6.2. This means that if you want to use RavenDB Cloud it will work.
