Good Morning,
Thought I might add one problem that seems to have arisen recently. I upgraded from a VC version that was a couple versions behind the most recent. I think it was from last October. I imported my old notifications when I switched from server 2008 to server 2012, everything seemed fine. However it appears that on a server restart, the imported notifications vanish and must be re-imported. The remedy of re-importing is easy enough, but forgetting leads to not being notified of errors, which is how I originally discovered the notifications had vanished.
