I have not been through this personally, but I believe you are correct in that all you need are valid PDU's, and to complete the application process again. Just make sure the projects you use in your experience are recent enough to qualify. Best of luck to you!
I was cleared to take the PMP exam. I took the exam once, did not pass, and my one-year eligibility passed.
Do I just get my PDU's, fill out the application with my Projects as before and submit the application again?
