Further to my previous database issues, which I think I resolved (I've compared the schemas of a clean install 5813 and my upgraded version and at least structurally,
I think they're the same), I now have issues with the agents connecting:
I think the issue was the fact that the attempted database conversion failed and
some values were not placed in some columns, causing the code to barf, as it
should; however, maybe some note related to these changes would have saved
me some time.
