Appointment & resignation of directors

Dear all,

Please clarify on mentioned query:

A Company has two Directors and want to appoint a new Director replacing one existing Director.

Whether the following procedure can be followed:

1. Hold Board Meeting to consider the matter and to approve notice of EGM.

2. Hold EGM and pass resolution for both Resignation of existing Director and Appointment of a person as regular Director.

3. File Form 32 within 30 days of EGM for both Resignation and Appointment.

What will be the effective date of resignation and appointment?

Thanks in advance
