Hi.

Can you please tell which counselling are you referring to? So that we can provide a more comprehensive answer.
Meanwhile, all counselling usually have an option for seat upgradation if they accept the seat offered to them in the 1st round but it also depends on what counselling option did the candidate opt for at the time of accepting the seat.
