It’s not a technical problem. IBM and whomever owns other “undead” platforms aren’t dumb, they price the stuff high enough to print money, but low enough to make it a poor return to migrate.
In a big enterprise, the mainframes give CIOs leverage for other stuff too - they sell at high margin and IBM will “give away” or subsidize other services by moving money around in the backend.
