Abstract
A method for updating a destination volume, the method may include monitoring duplicate traffic that represents original traffic that is exchanged between at least one host computer and a first storage system; wherein the monitoring is executed by a controller during an execution of a migration or a replication of a source volume of the first storage system to a destination volume of a second storage system; wherein the controller is not included in the first storage system; wherein the original traffic is related to the source volume; wherein the duplicate traffic is sent toward the controller by at least one switch that attempts to duplicate the original traffic; and controlling, based upon the monitoring, a process of updating the destination volume with a set of source volume updates, wherein the set of source volume updates are reflected in the duplicate traffic and are received during the execution of the migration.
