This operation is used when unfederating ArcGIS Server with Portal for ArcGIS. It removes any items from the portal that represent services running on your federated ArcGIS Server. You typically run this operation in preparation for a full unfederate action. For example, this can be performed using My Organization > Edit Settings > Servers in the portal website or the Unregister Server operation in the ArcGIS REST API.

Beginning at 10.3, services are removed automatically as part of the unfederate process. If the automatic removal of service items fails as part of the unfederate process, you can manually re-run the operation to remove the items from the portal.


The Unfederate operation does not remove any items representing services published by portal users (in other words, services in the Hosted folder on ArcGIS Server). Those services are entirely managed by the portal.
