Legacy Systems Modernization is not simple : is Claude Code COBOL Modernization a useful tool or Hype?
In previous posts titled Anthropic code or Hypethropic code? and Anthropic code: No Revenues Plan as Immaturity i ndicator I was very skeptical about current Anthropic code capabilities. This post is about the unrealistic dream of transforming Legacy Mainframe COBOL Systems to modern systems by using Claude code COBOL tool. More than 50 years ago I was a COBOL Programmer. Afterwards I was a Systems Programmer and a CTO. I participated in Mainframe systems architecture changes, replacement and maintenance, as well as Mainframes migration projects and Modernization projects. The main issues are not pure coding issues. Some of the major obstacles will be dwelled upon in the following paragraphs. Functionality and flow of the System Usually nobody knows and understands it completely.
