There shouldn’t ever be a sibling in a counter object, so that _should_ work.

However, since you've mentioned copying from cluster to cluster, expect a sales call any minute…to preempt that, let me tell you about a wonderful piece of software we sell at Basho that could solve this very problem for you…
