Ok, when we switch from Test Center to a regular city and vice versa we have to download patches/updates. What happens each time we do this? Do the patches just keep adding on to each other or do they get uninstalled when you go from TC to another server? I ask because I was just trying to go from TC back to DG and I got an error message that I was low on disk space and so I can't run the patch. I'm about to go uninstall some programs I have to help things out, but I am still wondering about the whole patching process. Anyone have any other solutions?
