1. An apparatus comprising:
at least one processing device comprising a processor coupled to a memory;
said at least one processing device being configured:
to generate a current snapshot set for a consistency group comprising a plurality of storage volumes subject to replication from a source storage system to a target storage system;
to compare one or more configuration attributes of the current snapshot set to one or more configuration attributes of a previous snapshot set generated for the consistency group;
to detect a change in at least one configuration attribute of the current snapshot set relative to the previous snapshot set based at least in part on the comparing; and
to communicate the detected change in the configuration attribute from the source storage system to the target storage system so as to permit the target storage system to implement a corresponding configuration update for the consistency group;
wherein implementing a corresponding configuration update for the consistency group comprises updating an active snapshot set for the consistency group in the target storage system to reflect the change in the configuration attribute.
