From https://community.esri.com/ideas/12258-arcgis-pro-publish-services-to-arcgis-server?messageTarget=al... I can now publish and overwrite a map/feature service. However, when I right-click on a GP service on an unfederated server, there is no "Overwrite" as there is with a feature service. Do I need to be right-clicking somewhere else? If I right-click on the GP tool results in history, I can share it with a FEDERATED GIS server, but there's no choice for any of my unfederated servers, which doesn't help me in either case as I'm needing to overwrite (update) the GP Service.
