Abstract
Exemplary method, system, and computer program embodiments for, in a data storage environment configured for synchronous replication between a primary and secondary pair of storage entities, each having tiered storage devices, extent migration are provided. In one embodiment, by way of example only, a migration instruction is sent, by the primary storage entity, to the secondary storage entity, the migration instruction including a relative priority based on a primary ordered heat map of the tiered storage devices of the primary storage entity. The relative priority is used against a secondary ordered heat map of the tiered storage devices of the secondary storage entity to perform the extent migration, regardless of whether the primary and secondary storage entities are identical.
