Hello,
We have moved our enterprise to a new environment (New servers, new version, new URLs). Before adding the new components, I wanted to clean up by getting rid of the old system. I have unregistered the Portal and Server components from ArcGIS Monitor, but I still see the Services associated with those sources listed and no way to unregister or remove them. I could not find anything in the documentation, Technical workshops, nor the Esri Community. Is there a way to do this, or do I have to blow out the Postgres database and start over?
