Typically, in case of legacy systems or when functionality has changed beyond a point the current system can not function,re-engineering techniques are deployed. Often, inadequate documentation exists necessitating our experts to do reverse engineering to identify functionality and logic of the system. Once the functionality is identified and documented, the system can be rebuilt to confirm with the new requirements. The latest technology and designs are built to get higher throughput and performance.
