Hello Aspirant,

Since you have not mentioned the name of your state for which you are going to appear for NEET Counselling so it's quite difficult to guide you with an accurate information.

Generally you have to first of all follow the complete admission procedure for the allotted college and then you have to apply for seat upgradation and don't worry if the seat would be upgraded then you don't have to pay the fee again because the fee you have paid for earlier allotment will be refunded to you and the documents which you have submitted in the earlier college which has been allotted in earlier round will be given back to you to submit in the newly allotted college.
