I've started to go through my 10.9.1 services and change them via Manager over to the Pro runtime. One thing that I thought would happen would be for the "./directories/arcgissystem/arcgisinput/foldername/service.MapServer/extracted" v101 folder and its contents with the .msd and .mxd files to be migrated to a p20 folder and .mapx file. This doesn't seem to be happening.
I was hoping to be able to use the resulting .mapx files to replace my old mxd project files in the likely cases that I'll need to republish various map services with updated symbology, layers, etc... As is, it seems that even though I've changed the runtime for these services to the Pro runtime, I don't actually have any working map documents in Pro. Am I forced to copy the mxd that is still in that "extracted/v101" folder and manually go through the full Pro migration with those, one at a time? If that's true, would the manual migration process from mxd to Pro produce the same map that Server is now using with its Pro runtime (after changing the runtime from ArcMap to Pro from within Manager for each service)? Also, what would happen if someone tried to republish to a service with their mxd after I've changed the runtime to Pro?
Thanks.
