We are trying to troubleshoot an issue on a Production Enterprise Deployment of 10.6.1 (Single Machine deployment) which we believe is related to SSL Certificates.
To allow safe troubleshooting we have cloned the machine and stood up another VM with a copy of the deployment on a new VM. We have certificates made for the new machine which have been bound at the web tier level and imported into server/portal.
The issue we are having is that we are unable to change the hosting / federated server to the new cloned server. We have followed the documentation but there is not an option to "Join Site". When we try to add the new server via the portal setting site it says "ArcGIS is already a federated server".
We have considered un-federating the existing server but there are many warnings on this site suggesting it will cause multiple issues.
What are the steps to follow that will allow us to clone an existing 10.6.1 Enterprise Installation to a new Virtual Machine and configure it to point to the new cloned ArcGIS Server machine?
