Over my 30 years, mostly in Fortune 250's, I've seen 3 mainframe migrations fail. If you're part of the team, the trick is to get another job before people realize -- in year 4 of your "5-year" migration -- that it was never going to work, because managers in other parts of the business will never allow their headcount to be reduced by better IT workflows.

Having worked adjacent to some of these kinds of projects, can't upvote this enough. Not to mention that business doesn't take the suggested 1-2 years to simply document and define test cases for the old/new system to ensure such a new system works, and simply start working on the new system based on what the business/da types drew up. Missing literally tens of thousands of legal edge cases defined in the legacy codebase.
