The TL;DR: Does anybody know if there is a workflow to join an existing ArcGIS Enterprise machine to a Windows AD Domain?
I've got a single-machine-deployment of ArcGIS Enterprise (Server, Portal, Data Store) running on a Windows server in AWS that is not part of an Active Directory Domain. My goal is to move the ArcGIS Server Site to a new machine. Esri's support has explained the only way I can move an ArcGIS Server Site to a machine with a different host name is via the join-site and migrate procedure. Of course this requires the server directories and config-store folders be placed on a network file share available to both the existing machine and new.
The problem with this is that the only way I could do this is to create an AD Domain server, and add both machines to the domain. Unfortunately. adding the existing ArcGIS Enterprise machine to the AD domain complete broke ArcGIS Server. In my haste to restore the machine from a snapshot I failed to get a copy of the logs, but there were a lot of Java RMI errors that contained the new fully-qualified host name of the machine (including the windows domain name, e.g. "hostname.domain.local").
I suspect the server runtime is looking for configuration filenames or values based on the FQHN, as opposed to just the hostname.
Cheers!
