Hi all, I'm looking for a bit of help regarding migrating to Enterprise. Our organization is updating to ArcGIS Enterprise from a standalone 10.4.1 server. We are adding another machine to help with arcgis server load and installing the base deployment on it. Our current 10.4.1 ArcGIS Server machine also acts as a webserver. I was thinking option 3 would be the best option below as I plan to federate this machine to the new base deployment in order to not have to republish services. Right now the 10.4.1 server has webadaptor, arcgis server and hosts our website. Would there be any issue federating this server to the base deployment? Or should I upgrade in place and use the new server as an added hosting server. Since the 10.4.1 machine has our ssl cert, external website and webadaptor, perhaps Enterprise base would be best installed on this machine?
"The result of Option 3 is a base ArcGIS Enterprise deployment with an additional ArcGIS GIS Server site. Option 3 uses new infrastructure for the base deployment and upgrades your existing ArcGIS Server site to a federated GIS Server site within the ArcGIS Enterprise deployment. As in Option 1, the key benefit of Option 3 is that it does not require that existing services be republished, and service URLs are not changed. However, because you are adding new, separate, infrastructure for the base deployment you will need to purchase additional cores of ArcGIS Server."
