I have a request to add Pipeline Referencing extension to a ArcGIS server. I went to add it, but I already have Roads and Highways extension on this server. During install It states "Choose from either Roads and Highways or Pipeline Referencing but not both".
Is the only solution to add another ArcGIS Server, to be able to add the Pipeline Referencing extension?
Yes, one instance of ArcGIS Server can support either Roads and Highways or Pipeline Referencing. If you'd like both capabilities, you will need two ArcGIS Server instances.
