I have been trying to figure out why after upgrading from ArcGIS Enterprise 10.6 to 10.6.1 all my hosted feature services published before the upgrade are treated like regular feature services in ArcGIS Portal but are still treated like hosted feature services in ArcGIS Server Manager. All hosted feature services published after the upgrade are operating as expected.
I did some comparisons of the JSON of hosted services before the upgrade and hosted services after the upgrade. The formatting of the JSON is very different between the services before and the services after. I have even found hosted services with the "currentversion" value listed as 10.31, 10.5, 10.51, 10.6, and 10.61. I do not know how we have hosted feature services at version 10.31 since we did not start using ArcGIS Portal until 10.5, but our ArcGIS Server was originally at 10.31. My guess it that ArcGIS Portal 10.6 and older could understand the JSON format of the older hosted feature services but ArcGIS Portal 10.6.1 cannot. The config-store for ArcGIS Server has the currentVersion listed as 10.61. I have always had trouble getting the "Complete Upgrade" part of the ArcGIS Server upgrade process to either run at all or run correctly on our server.
Does anyone know how to manually force ArcGIS Enterprise to upgrade a hosted feature service's JSON to the current version?
