I did such a migration. End results :
- user security massively increased (they need hardware tokens)
- user management is now part of a globalized management system where control access are much stricter than (let's call the dev to add somebody)
- it is muuuch easier to find new Java devs; development is now shared between the company (for business knowledge) and another company for the development, diminishing the train factor by a huge amount.
- code has been modernized and so is much more easy to audit
- SQL database can be queried by armies of cheap data analysis tools
- some of the consultants have now much less power to negotiate their salary (less than they were only 3 managing the application :-) )
That were for the positives. Negattives:
- Java UI needs much more time to get polished or much better dev's.
- Security is now much more administrative. Gone the days of the quick fix in production.
- hardware token for security is not vey well handled, incurring a heavy toll on data access (a limitation of our security token, which was unfortunately not seen during project planning)
- we had to reproduce all the TUI shortcuts for people to stay productive. Yes, you read that correctly :-)
- nix23 5y agoIt sounds you had a much bigger budget than we had ;) BTW, the Mainframe had a sql-database (DB2) and was attached to Active-Directory already, the Reports/Print-jobs where send to a Linux Machine, it was actively maintained and not some old crusty 70's System.
- rbanffy 5y agoThe only sad part here is that you didn’t get your own 3278 with beam spring keyboard ;-) People often equate a later fad with “modernisation” when a well architected app can be easy to manage even if written in COBOL and running under CICS. If a person can learn Java, they can learn to read COBOL.
