Software Legacy systems typically refer to large, complex systems that have evolved to a state where they significantly resist further modification and evolution. Over the past decade, the life of many of these cash cows of the software industry has been extended by migrating them to modern platforms. Recently, in part due to the proliferation of the Web, those same systems seem to be morphing again into highly configurable systems of systems. According to a recent SEI study, software-intensive systems of systems are likely to evolve into Ultra-Large-Scale (ULS) Systems. In this talk we will argue that software-intensive legacy systems need to morph into self-adaptive and self-managing systems to be able to cope with the challenges of continuous evolution.
