I will not be onsite, but I should be able to work remotely. I need for you
to dictate to me how the machines should be installed and leave the
installations to me.

As of now, sunday april 1 is clear. I would like to start no earlier than
noon EDT because the NOC staff will not be there before then should we need
NOC intervention.

I would like to see some kind of service migration plan for the outage. I think
we could do rolling updates, where we migrate services from one machine to
another, then reinstall the OS, then migrate services back, and so on.
