I moved my 10.3.1 Server and Image Extension to a new virtual server, which leaves me with the old physical server as a development server for 10.5.1.
I ran an update to ArcGIS Server 10.5.1 on the old 10.3.1 install, and it seemed to work. Now, in order to test Image Server, how do I install it on the same machine, since it is just a licensing variant of the ArcGIS Server install?
I want to thoroughly test 10.5.1 before I move it to production, because my SQL database will need an upgrade too. Can I do this on a single machine? Or is it mandatory that Image Server run on a separate machine?
