A lot of the problem stems from the databases. COBOL, and these legacy systems, pre-date relational databases. They work with proprietary and custom file formats, which COBOL was designed to work well with. Regardless of technical debt or scaling problems, the data in these systems has tremendous value, and converting it to a modern relational structure is a bigger job than fixing some bugs in COBOL code.
