Hey,

Round 1 has free exit, hence there is no fees for upgradation. If you report to the allotted college in Round 1, you have to submit willingness for second round up-gradation as Yes. If you desire to take part in second round of online allotment, you will have to submit fresh choices during choice submission  period and lock the choices during period of locking. Once you join second round seat, you will not be allowed to vacate from allotted 2nd round seat.
