Zusammenfassung:	Various method, system, and computer program product embodiments for facilitating upgrades in a computing storage environment are provided. In one such embodiment, one of an available plurality of rolling upgrade policies is defined by specifying the at least one selectable upgrade parameter, including specifying one of a commencement time and duration of an upgrade procedure. A node down tolerance factor is set for at least one node in the computing storage environment. A determination of whether a number of at least one of a plurality of nodes in the computing storage environment currently down, including a target node to be upgraded, does not exceed the node down tolerance factor, and if the node down tolerance factor is not exceeded, a cluster health is checked.
