PMP Exam Validity

Dear All
Hope you are doing well. I have a query.
I have paid exam fees last year for the PMP certification. The validity of the exam would be over next month. The query is:
If I am not able to take the examination in the validity period, after my exam vailidity period is over do I need to rebuild the entire application, submit it for approval and then pay the fees OR just that I can re-pay the exam fees only and keep the existing application alive and appear for the exam later.
Kindly suggest.
Regards
Jay
