  * Copy resources
  *
  * This command copies all resources from one collection to another storage identified by name.
  * The target storage must be empty and must not be identical to the current storage of the collection.
  *
  * This command merely copies the binary data from one storage to another, it does not change the related
  * PersistentResource objects in the database in any way. Since the PersistentResource objects in the database refer to a
  * collection name, you can use this command for migrating from one storage to another my configuring
  * the new storage with the name of the old storage collection after the resources have been copied.
  *
  * @param string $sourceCollection The name of the collection you want to copy the assets from
  * @param string $targetCollection The name of the collection you want to copy the assets to
  * @param boolean $publish If enabled, the target collection will be published after the resources have been copied
  * @return void
