Hello Rony, Legacy applications may not be the most aesthetic, but they are often quite efficient and when moving from legacy to GUI or WUI (Web user interface), keeping the efficiency can be quite a challenge. If you are looking at applications like order-entry or financial apps where people are working with forms and data all day, then you might consider minizing keyboard-mouse transitions (those are slow), examine workflow and optimal layout of required and optional fields. For the highest frequency operations, it might be useful to gather some baseline data for comparison. Youl could also use the GOMS Keystroke-level modeling to compare different designs for your Web interface. The GOMS KLM is quite powerful for doing relative comparisons and examining expert usage.
I went through this in the early 1990s when legacy moved to Windows and for those will admit it, the first Windows versions of legacy app were often worse than the legacy app even if they "looked more usable". Here is a note that I wrote in respone to a question like yours in the STC Usability SIG newsletter in 1998.
