Hello , 

As your query is you want to know that you have to pay the fee of seat allotment in DU JAT in the first round or not if you want to go for upgradation. 

I would like to tell you that after every round of counselling if you want to upgrade you have to provide the counselling fee of every round but in any case if you don't want to go with the seat allotted to you then you don't need to pay any seat allotment fee to that in corresponding but since I have mentioned if you want to go for the upgradation then it is a must case that you need to provide the the counselling fee. 

Thank you.
