      With the implementation of "PM-2323 No More Auto-Splitter (Milestone 1)" in 6.0 we broke the old procedure used in the field to pre-split and distribute chunks of an empty collection.
      This procedure was used to speedup the initial bulk-loading of data into a collection and is also described in our official documentation.

      Starting from 6.0 customer can't rely anymore on this approach since the balancer won't automatically distribute chunks for an empty collection. (data-size based balancer).

      As part of this ticket we should test and document a new approach based on moveRange and update the official documentation.
