What happened to marketing? You should _never_ say "X is going to be closed on Z date." You say "we are upgrading X to be more like what it was before, but actually work on Z date." Then have your army of service and support personnel get everything moved over, seamless to the user.

'Copter, because no one will know who does the actual work.
