I have a few map services that I would like to move to ArcGIS for Server 10.2. Each server is on a separate machine. I have come across instances where people migrate the entire arcgisserver folder, (arcgisinput, arcgisoutput, cache, etc.) however my 10.0 services only maintain an input and an output.
What's the most time efficient manner in migrating single map services and not an entire instance from 10.0-10.2?
