Upgrade from 7 to 8.0.2

We are trying to upgrade One identity manager from 7.1.2 to 8.0.2

We found that AttestationHelper table is missing foreign key relation to  uid_pwodecisionstep in new version. How we can fix/address this. We have many customizations in WEBUI and Backend processes that are failing compilation because of this.

Thank you
