I am publishing a ArcPy Mapping script to Server that modifies the legend style for layers in a map document. I have this working great in ArcMap using a custom .style file but when I publish to Server the instructions say I have to convert my custom .style file to a .ServerStyle file. I have found some very old instructions (9.x) that say to use a utility (MakeServerStyleSet.exe) to convert the .style to a .ServerStyle. I can't find this utility anywhere in 10.3.1 or 10.4.1. How do I do this?
