copy group or container cascaded with the initial copy group or container (cascade destination
group).
The following are supported combinations of copy groups and containers when defining cascade
configurations:
• If the target group is a local copy group, it can only be combined with a following group that is
a remote copy group.
• If the target group is a local copy group container, it can be combined with a following group
that is a remote copy group container.
• If the target group is a remote copy group, it can be combined with a following group that is a
local copy group or a remote copy group.
• If the target group is a remote copy group container, it can be combined with a following group
that is a local copy group container or a remote copy group container. In addition, the target remote
copy group container can also be combined with a following group that is a local copy group.
