I work in a company where we own an Arcgis Enterprise standard (ArcGis Server, ArcGis Portal) version 10.5.1
it is working on our virtual windows machine.
Now we want to upgrade to version 10.7.1.
We want to install all the new software on a new vitrual machine, copy everything there and test how everything is working while letting our main server running.
The question is if it is possible from the Licencing point of view to have 2 servers running simultaneously?
