I was waiting for someone else to offer a better option than I’ve got, but that hasn’t happened.
This may not be elegant, but I think it’ll work. Backup the “new” priv.edb as it stands right now. Restore the old pub.edb, and then restore the new priv.edb. This should put the hooks from the new priv into the old pub.
Disclaimer–I would test this procedure on a test machine first.
