Shram suvidha portal return file required - return submitted on existing portal of pf and esic?

I have registered under pf and esic act. upto july-17 i filed my pf esic return on existing portal of pf and esic.
is required to file return on shram suvidha portal

you can either use shram suvidha portal for combined challan of esic and epf or use the existing portals of both, however every soon the existing portals will get closed and return would get filed with shram suvidha portal only,

IF its sure then, is new Establishments can directly make registrations of both ESIC & PF from Shram Suvidha?? I think it will be convenient for new registrations..
