I published a cached map service with set of attributes. I need to add / remove published attributes, but I want to use old cache, because there was no change in the geometry. Is there a way how to use old cache? I tried to create new service and copy cache into its cache directory, but ArcGIS seems to recache anyway.
Just overwrite the existing service when you begin the publishing, and when you do that you are given a chance to keep the existing cache or delete it. Tell it to keep it. It's super easy.
