The only way to integrate legacy systems with modern databases is slowly. Trust me -- if you've been in business as long as I have, don't expect this to be done in a day or two. Chances are, you've not got one, but several old data storage systems. Worst case? Some of that historical information is even on (gasp!) paper. So, however long you think it will take, double the time frame. Once you get into the process, you'll come across caches you totally forgot about, and if you're on a tight deadline, skipping sections will be tempting. For an effective result, you must plan ahead, and book enough time to do it right. Linn Atiyeh Founder & CEO, Bemana https://www.bemana.us/practice-area/industrial/
Integrating legacy systems with modern databases was like solving a puzzle with pieces from two different boxes. We developed middleware that served as both a translator and a bridge, allowing all pieces to fit perfectly. This task brought out the determination and analytical skills within our IT team. The key insight we gleaned was technology, regardless of its age, can communicate effectively when a common language is established, handled by an innovative and relentless team.
