What type and how much training do the end-users need to be productive with the converted system?

Actually the impact on end-users is minimal! We do technological modernization so we replace the platform (database engine; programming language; etc.) while keeping the functionality of the legacy application unchanged. It means that the converted application provides the original identical output for the users both on the screens in on-line mode and also in batch mode. The end-users can practically work with the converted system without any training. There might be some minor changes like accessing the business functions on a webpage instead of on the 3270 terminals, or accessing batch/print files in a different application than before, but the functions and flow remains the same.
