PF Balance Withdraw from 2007

My father worked in a company till 2007 when EPF balance used to be on papers, not digital. From 2013 to 2019, he worked in a company when EPF was started to be given digitally using a unqiue UAN. We have been able to withdraw the PF balance from 2013 to 2019 digitally by filing the suitable forms. How can we withdraw the amount of earlier period? We have proof of PF balance written on papers which was given by the previous company.
