Shift from angel bee to angel one

My angel bee app shut working today, came as a surprise since i wasnt aware of a migration being acrried out to angel one. when i called helpline they said, a from will be sent which i need to print and along with aadhar and pan send it to angel HQ in hyderabad for doing the shift and opening demat. Is there a easier way of opening for folks in mumbai and also wondering if the investment made through angel bee is safe
