In the presence of modified user requirements, deployment environments, and bug fixes, actively-used software must be upgraded continuously to ensure its utility and safety. The upgrades incorporate changes to the structure, behavior, configuration, data, or topology of a computer system. Whether applied offline or directly to a live system, such upgrades may have a significant impact on the performance and reliability of the software. Indeed, recent studies and a large body of anecdotal evidence suggest that, in practice, upgrades are failure-prone and can lead to outages, data corruption or latent errors. These problems not only inconvenience end users - they create a significant burden for organizations due to the associated downtime and high administrative costs.}, keywords = {software, upgrades}, isbn = {978-1-60558-768-4}, url = {http://doi.acm.org/10.1145/1639950.1639974}, author = {Tudor Dumitras and Neamtiu, Iulian and Tilevich, Eli} }
