    Description

      The _configsvrCommitChunkMigration command, which is used to persist the new owner of a chunk after a migration performs one extra lookup of a chunk in order to verify that the collection epoch has not changed.

      Given that we already find the highest chunk for a collection a little bit after, this call is not necessary.
