You should take a look at my company. Heirloom Computing. Heirloom.cc We have migrated many mainframe application and millions of lines of cobol and pl1 into Java and deployed it into production on prem and into the cloud.

It's a demo but the code that is transformed is trivial in the extreme. The whole approach of selecting small pieces is just not scalable. One small project i worked in was 22 million lines of cobol code, spread over 4000+ programs ima

Correct, language transpilation is the easy bit, ensuring that execution and behavoir is the same as on the mainframe is tough, but also solved.

Heirloom Computing, I am CTO, have transpilers for cobol and pl/1. code transpilation is the easy part. Create a Grammer for the source language, generate the ast, transform the ast to the target language ast and generate the code. Now

Heirloom computing where I am cto does this using transpilers with 100% automated transpilation. Using LLMs for an entirely deterministic domain borders on the insane. This is just marketing bs but we get asked about it and what our plan is

Or any of the companies that can run mainframe COBOL and provide all the ecosystem. heirloom computing is of course the best (i am cto) but Micro Focus, lzlabs etc all enable you to run off mainframe with a full ecosystem. Do not know about

well they still run on the mainframe, many of which can sit under your desk nowadays like a standard tower. but there is a whole industry about replatforming and refactoring these apps to modern infrastructure and software stacks.

its not so much COBOL, its the mainframe environment that is brilliant for critical stuff. My company migrates mainframe applications to the cloud so we find all kinds of reasons for clients to move, cost/skills/scalability etc bu

well i spend all my time moving people and applications off the mainframe so probably not the best person to ask, however a quick google of mainframe jobs showed up 100's (for experienced people). I have heard some large companies are

In a word no. There is a place for LLM in mainframe migrations but it is not in source code transpilation. COBOL (or PL/1) to any other language is a deterministic problem, imagine transpiling millions of line of code and every time yo
