If you upload a different (newer) version of your raw data, there might be many different SNPs. Some SNPs might also have been removed in the updated version of your raw data. The best option would be to create a separate profile for your new raw data, purchase a gene report app and upload the file there.
I uploaded my genetic raw file about 2 years ago I think. If I upload my raw genetic file again now, will any extra snp's be available?
