Simple, switch when they find something that fits their need. They don't have to switch everything at the same time. And it's not just about switching technologies, it's probably also about fighting against pushbacks ("lobbying", etc), dealing with training, and other unforseen (at least to the layman) things that happens when a huge entity starts pulling away from microsoft. I don't think there are degooglify/demicrosoftify-yourself manuals at the state level.
