We migrated several tile caches from an old ArcGIS Server machine to a new one. All worked fine until today, when for some reason they will not display via REST services. They are up and running, and display normally in ArcCatalog, but if I go to my REST services directory, none of the tiles will show up. The common factor among these services is that in ArcGIS Server manager all of the troubled services have references to a "service workspace" that's located on a server that we recently retired. I can't figure out how to remove the reference to the old data. The feature class that the service workspace references is a layer that is not needed at all; furthermore, I was under the impression that if it's a cached service then there's no need to have any reference to feature classes.
