Have you actually tried that? Open DB1 in PT2, Utilities >Export HH to File.. - it will create HH's from the DB1. It doesn't care if you saved the originals, it creates HH's from the data in the DB. Import to DB2.
You realize you would get a faster, more accurate reply if you just asked PT support, instead of some random 2+2'er like myself (who obviously has no clue wtf he is talkin about).
