What's fascinating, and probably points to how young&naive IT org management also tends to be is ... how many let themselves be sold on these solutions.
Oh you are going to rewrite established solution X in Y in 2 years with 5 devs, and it's going to solve all of the problems we have in X, awesome!
Ignoring that solution Y is so new that the guy proposing it has never actually delivered an enterprise solution in it. And since they just got hired, they have no idea what the user facing problems X is actually exhibiting. Often the problems with X are organizational, managerial, and prioritizing. Switching tech doesn't magically change the decision makers.
Invariably hiring a guy who has a string of 18-24 month jobs on his resume, which, uncannily, is the typical runway of a Greenfield re-write project before heads roll.
