Modernization Is Not Migration

Industry Context Modernization used to mean something simpler: Move the workloads, update the tooling, declare the project done. In practice, that approach meant engineers manually migrating hundreds of DataStage jobs one at a time, a process that was slow, error-prone, and impossible to scale as platforms grew. The traditional model worked when volumes were low. It broke entirely when weekly release windows started carrying 500 jobs, and the only way through was brute-force manual effort.
