Unfederate ArcGIS Server site that no longer exists

[SebastianCabrera]

Hello, 

I´m trying to unfederate an ArcGIS Server site (geoevent) that no longer exists from my Portal (both 10.5), but the portaladmin interface doesn´t allow to remove de server if it doesn´t exist, it seems that the site must be online in order for the unfederation process to work. Is it right?

Thanks

Did you try removing it from Portal website (My Organization > Edit Settings > Servers)?

You can remove it through the Sharing API:

https://<portal>.<domain>.com/<context>/sharing/rest/portals/0123456789ABCDEF/servers/<id>/unregiste...

This is only something that should be done if you know that the Server should no longer be federated to Portal.  You shouldn't unfederate as part of a troubleshooting process for your Portal and Server.  If you're troubleshooting something and considering unfederating, I suggest you reach out to Technical Support first.

Thank you very much, this worked for me, since the server was decommissioned before being unfederated from Portal

What would I do if I have the reverse situation.  Portal no longer exists but ArcGIS server does exists and the server  is still federated with the non existing portal.

That is how do I unfederate a server when the portal no longer exists?

You should go to the ArcGIS Server REST admin API, https://<yourarcgisserverfqdn>:6443/arcgis/admin/security/config and change the server role to standalone server, and authentication tier to GIS Server.

That should work

Thank you Sebastian, that worked perfectly.

Much appreciated
