Hello dear ESRI community!
I've raised an ArcGIS enterprise production environment with ArcGIS Server on one machine, ArcGIS Portal on another machine and web adapters on third machine...the is environment federated.
i created a new server and transformed a complete image of above production portal machine which was federated with above production server. I unfederated the ArcGIS server from this new imaged portal on new machine. This actually unfederated the server from above production environment. and i am in big trouble now. Actually, I can see the Production Server in Portal Organization under Servers but it not validating. Similarly, i can see the Production Server in ArcGIS Server Administrative Directory but again upon validating it is giving error "failed" saying the TOKEN is not Valid or Expired.
Can anybody ESRI help me out please and advise me how can i recover federation in the production environment.
