To play devils advocate, those same detractors would claim that the real issue will be in the coming year. That the migration is a good chunk of work, sure, but the real challenge will be decaying hardware, operational issues related to firmware upgrades or having spares on hand or replacement parts that get discontinued by the manufacturer. That said, I am personally very happy to watch this, as a "cloud skeptic" myself.
