This module discusses information about multi-target and cascade configurations and procedures for
creating them. The following topics are included in this module:

About multi target and cascade copy pair configurations
Using the Pair Configuration Wizard you can define multi-target or cascade configurations that consist
of multiple copy pairs and copy groups, in a single sequence of operations. The following are sample
multi-target and cascade configurations:
There are some requirements for copy types of the pair groups that can be added in multi-target or
cascade configurations, to be compatible with the copy type of the original pair group. In this case,
the copy type of the pair group to be connected by the Add Group operation must satisfy these
requirements to be compatible with the copy type of the original pair group. For details on copy type
requirements, see “
Copy type requirements for pair configuration definitions ” on page 166.
