Appointment of auditor

A partnership was appointed as the auditor for a period of five years after commencement of Companies Act, 13. Where in Details of Mr. A (CA, partner) was provided in form ADT-1 along with other details of the Firm.

Now Mr. A (CA) has left the partnership in the firm.

My question is whether a fresh form -ADT1 has to be filed  or the continuing partner of the firm can sign the Audit Report.
