- collection (string) – Specify the sharded collection containing
the chunk to migrate.

chunk. Typically specify the shard key for a
document as the query.

Moves the chunk containing the documents specified by the query
to the shard described by destination.
This function provides a wrapper around the
moveChunk. In most circumstances, allow the
balancer to automatically migrate chunks,
and avoid calling sh.moveChunk() directly.
