HG19 vs HG38 genome and SNP refinement.

Can someone explain the difference in results by switching from HG19 to HG38 genomes? I know that a few of us have seen elimination of prior positive SNPs and also addition of many negative SNP's and some new positive SNPs as well. Some who have had the eliminated positive SNPs tested at yseq report they are still positive there.

Also is there anyway to tell who has been re-worked under HG38 vs HG19. Seems like it would be apples to oranges comparisons if some have reprocessed and others in a given project haven't.
