Switching frameworks for any large system is non-trivial not so much for the technical effort necessary but for the political effort. For any large enough system (if it were small, you could make changes and nobody would care), you're going to have to persuade the stakeholders why they need to switch. That's not something you can do with a low-touch message to everyone in the project. That's a "let's sit down with people, listen to them, figure out how we can find common ground" high-touch strategy. Even if you get everyone on board, it still took a long time.
