Anyone who has worked with me knows that I have no issue coming in like a wrecking ball in order to make things happen, when necessary. I've also been involved in some of these migration projects. I think your take on the complexity of these projects (and I do mean inherent complexity, not incidental complexity) and the responses you've received is exceptionally naive. The amount of wise-cracks and beers your team can handle after a work day is not the determinate factor in success. /Most/ of these organizations /want/ to migrate these systems to something better. There is political will and budget to do so, these are still inglorious multi-decade slogs which cannot fail, ever, because failure means people die. No amount of attitude will change that.
