Despite major advances in the engineering of maintainable and robust software over the years, upgrading software remains a primitive and error-prone activity. This paper argues that several problems with upgrading software are caused by a poor integration between upgrade deployment, user-machine testing, and problem reporting. To support this argument, a characterization of software upgrades resulting from a survey conducted of 50 system administrators is presented. Motivated by the survey results, Mirage is presented, a distributed framework for integrating upgrade deployment, user-machine testing, and problem reporting into the overall upgrade development process. The evaluation focuses on the most novel aspect of Mirage, namely its staged upgrade deployment based on the clustering of user machines according to their environments and configurations.
