I know there are two options to create WGS services if your data is in a different coordinate system (like State Plane): Reproject the data to WGS or to change the mxd to on-the-fly transformation. Both have their advantages and disadvantages, the former is time-consuming and the latter comes at a performance cost.
I assume there are a lot of sites out there that have their data in State Plane (or other) coordinate system and publish map services as WGS for sharing etc. Which one of the two options is best practice or commonly done.
