Abstract
Techniques for CDP/R services are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method of transitioning continuous data protection and replication comprising determining whether a first appliance node connected to a switched fabric contains one or more transactions received from a host node, unregistering a world wide port name of a target port of the first appliance node, registering the world wide port name to a target port of a second appliance node connected to the switched fabric, associating one or more logical unit numbers of the second appliance node with the target port of the second appliance node, exporting the one or more logical unit numbers of the second appliance node, logging the target port of the second appliance node into a switched fabric, and logging the target port of the second appliance node into a remote node port of the host node.
