Cisco Security Manager Upgrade Note

When I am doing CSM upgrade from 3.3.0 to 3.3.1, it requires all pending activities being submitted or discarded.  Tried in File -> Discard, did not work, until realized other users signed in.  Had to Go into Tools -> Security Manager Administration > Take Over User Session.  Basically kill others sessions, and redo the File -> Discard.  The installation went ahead after.
