Methods, systems, and products for detecting impact of operating system upgrades on software components. Embodiments detect the impact of differences between a current operating system and an upgraded operating system. The operating system is configured to provide a run-time environment. In one embodiment, a method comprises detecting a call from a software entity running on a first data processing system to the current operating system of the data processing system; recording the detected call in a data structure configured to contain one or more recorded calls; scanning the upgraded operating system on a second data processing system upon which the upgraded operating system is installed and running, before execution of the software entity in the run-time environment of the upgraded operating system, to identify the recorded calls in the data structure that are not supported by the upgraded operating system; and presenting an indication of the identified calls.
