A "revolution" which imposed from above is generally trash, for many of the same reasons that big-bang replacement projects fail. Incremental change is the responsible way forward; it will show you the costs of your decision, and give you time to understand the best practices which will mitigate these costs as you perform a gradual roll-out. Even the successful American Revolution was an incremental change: an effort to preserve a tradition which feted the traditional rights and liberties of Englishmen going back to the Magna Carta. The shift in philosophical underpinnings may have been radical, but the political culture barely changed at all.
