Bulk Upload into RM8

HI New Here ANy help is greatly appreciated..

I would like to set up something in RM8 to do bulk imports of pdf docs (500000) into RM8, no metdata but with only DocID and Doc type, Currently we are using the REST service API but need a better way to do it as a batch-overnight, have read that the Document queue processor or Dataport can be used, can anybody kindly explain how I can use them? 

Any docs explaining the process for bulk upload either manual or automated will be great as well.

Many Thanks,
