BTW, I can't imagine that IBM or somebody else have not figure a technological solution to this. The main trouble is that customers on the enterprise side of the world have no respect for developers, and fired them after years or just not care. Then, when in trouble, ask for external contractors that do not have the required knowledge (and maybe, not even the skills). For this to work, it need to engage the on-site developers + maybe contractor or hire some additional hands for the mechanical work. Do it well, and this is fairly cheap for the benefit. But this require to "do it well". And that is the "hard" part, because is the human factor the big issue here.
