A Johnny Cash 1968 Shirt is that replacing one of these legacy systems is like “changing the tire on your car while it’s in motion.” But, that analogy really doesn’t describe the complexity of the problem at all. Imagine having to replace your car’s frame while it’s in motion. The corporation can’t take a year off to do this, it needs to continue down the highway without sputtering while you replace the framework that not only holds the wheels in place, but restrains the powertrain, protects the driver, holds the wires in place, and keeps the road from rattling everything apart. I witnessed several attempts to replace these systems. Each team was given a large budget and told to make it happen. Spirits of young programmers were dashed against the rocks again and again by these projects. They eagerly dove in, and documented all of the functions that are performed by the legacy. Then they began to build replacement systems that must run in parallel to the legacy. Until the project is completed, these replacements must pipe information into and out of the legacy while establishing an entirely new framework.
