The irony that goes along with smooth migrations on production is this.

If the migration is smooth, no one knows how much effort, careful planning and execution went into the whole process. They just get a for your information mail that everything went smooth. No one, not involved in the process would know the scale of things; or what could've happened if the transition/migration was screwed up.

On the other hand if there are problems during the process and the tech team fights back, they indeed are the heroes. No one notices the silent crusaders.

No wonder then that all superheroes just smash stuff. Its only then that people notice that they worked so hard. Silent superheroes remain dead.
