I want to repoint my PI Vision installation to a different AF Server Host. I did this by launching PI System Explorer on the PI Vision server and changing the asset server connection to the new host. The new host connects successfully (according to PI Vision admin screens), but all of my displays disappear from PI Vision. When I switch back to the old host, I get my displays back. Why is this happening, and is there any way to retain my displays when changing hosts? I thought that the display configurations were stored in the PI Vision database, but that does not appear to be true.
