I am upgrading an instance of SDL Web 8.5 to SDL Tridion Sites 9.1 including Experience Optimization. This requires updating a configuration file for the presentation application (bin\config\smarttarget_conf.xml) for the .NET CIL (Tridion.SmartTarget).
What I can't find anywhere is instruction on how to modify the configuration for the updated XO instance now using elasticsearch instead of Fredhopper.
There are XML elements such as FredHopper that lead me to believe that the XML will have changed significantly but I have no reference documentation at all. The nearest I have come to SDL docs is: https://docs.sdl.com/LiveContent/content/en-US/SDL%20Tridion%20Sites-v2/GUID-2301148A-E3EA-43EF-A2FC-7D3C9BAEE8FF?docid=GUID-1B7E5ECF-E1EC-4EA2-AD18-37809635940D but it doesn't provide any XML details other than referencing the filename.
