An apparatus includes a processing device configured to receive a request to change a given storage network from a first to a second configuration, the given storage network being associated with a heterogeneous storage cluster comprising a plurality of storage targets and initiators having first network addresses in the first configuration. The processing device is also configured to generate a shadow storage network comprising second network addresses having the second configuration, to assign the second network addresses to a subset of a plurality of storage targets and initiators affected by the request to change the given storage network from the first to the second configuration, and, responsive to validating connectivity of the subset of the plurality of storage targets and initiators, to apply the requested change by unassigning ones of the first network addresses assigned to the subset of the plurality of storage targets and initiators.
