Abstract: In an information management system, a controller implements a heuristic bundle optimizer to facilitate a migration or other type of transition of at least a portion of a data center from a first configuration to a second configuration. The controller identifies a plurality of component bundling scenarios each specifying a separation of a given set of components associated with the first and second configurations into bundles for transitioning on a per-bundle basis from the first configuration to the second configuration. The controller also evaluates the component bundling scenarios, and determines an optimal one of the component bundling scenarios. The portion of the data center is then transitioned from the first configuration to the second configuration with the components being transitioned in the bundles specified by the optimal component bundling scenario.
