I was involved in this for a couple of years in the mid-90s working for a COBOL vendor helping people migrate from mainframes and minicomputers to what was known as the “open systems” (mostly Unix, with Windows NT rising) world, saving a somewhat jaw-dropping amount of cash in annual licensing and support costs.
Even back then, one of the major complaints was that companies refused to pay for training, hoping they'd find someone who already knew everything they needed. I heard multiple stories about people who told their employer that they were planning to retire, left on schedule after not finding anyone qualified to train, and returned later as a consultant at a significantly higher rate.
