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 160.
