Does automatic migration really work? Isn't there a lot of manual work to do?
Do the converted Java programs conform to an object-oriented concept?
Is the generated code maintainable and suitable for further development?
Which COBOL statements cannot be completely converted?
What about GO TO? In Java there are no jump statements available.
Do many "atypical" Java constructs arise during the migration so that the result is a COBOL program in Java notation?
Will my developers recognise the source code? How significant are the structural modifications?
Doesn't that result in a lot of clones?
Would it not be better to redevelop the code in Java?
Can Java developers familiarise themselves with the migrated programs without previous knowledge of the COBOL code or COBOL know-how in general?
I want to keep my COBOL developers. How difficult is it to train them in Java?
Are the converted programs not substantially slower? And do they not need much more memory?
What experience does pro et con have with software migration?
