The main problem I ever saw while attempting to migrate legacy(mainframe/db2) to modern (linux/java/oracle :)) systems was coupling.. there is so much customized, non documented, completely forgotten coupling between systems that is like changing engines on a plane (While flying!). I takes a lot of patience, attention to details, and computer arqueology skills. Still, it can be done, and it is very worth it $$ to the companies (and to me! $ :) |
