I agree with @paul_hilchey that there are issues with Access History. As he recommended, just wait for the 8.5p1 release.
The IdentityIQ 8.5 upgrade script itself has basic syntax errors. While the script looks fine for PostgreSQL, the rest of the database types have syntax errors during the upgrade from IdentityIQ 8.x to 8.5.
