DoD Legacy System Migration Guidelines

Abstract : DoD systems contain a substantial amount of legacy software that often needs to evolve or to be migrated to new hardware and software platforms. This legacy software is important not only because of the large scale of the investment that it represents, but also because it represents a baseline for future growth. The purpose of this report is to provide a set of DoD legacy system migration guidelines. These guidelines are built on lessons learned from actual legacy system migration efforts and they synthesize previous work on the disciplined evolution of legacy systems.
