Abstract
Most engineers would rather work on new systems rather than refurbish, refactor, or extend legacy systems, but these systems exist because they work. They may have out of data hardware, software, and construction, but if they are still in the field, they still operate. One of the major tasks for the MDRE team with a legacy system to be updated or upgraded (we’ll explore the difference in this chapter) is to understand which requirements stay and which requirements must be replaced with updated versions that drive the new capabilities, new facilities, or new equipment (e.g., new computer systems) to be infused into the existing legacy system.
