1. A method for migrating from a first asynchronous data replication technology to a second asynchronous data replication technology, the method comprising;
utilizing a host-based software component to asynchronously replicate data from a primary volume to a secondary volume, the host-based software component executing on a host system;
initiating, at time T1, tracking of post-T1 changes to the primary volume;
waiting for all pre-T1 changes to the primary volume to be propagated to the secondary volume;
when all pre-T1 changes have been propagated to the secondary volume, suspending operation of the host-based software component;
replicating all post-T1 changes from the primary volume to the secondary volume;
utilizing an enterprise-storage-system-based software component to asynchronously replicate data from the primary volume to the secondary volume without assistance from the host-based software component, the enterprise-storage-system-based software component executing on an enterprise storage system, the enterprise storage system having different hardware and functionality than the host system; and
terminating utilization of the host-based software component to asynchronously replicate data from the primary volume to the secondary volume.
