PCCN to CCRN - Certification Question

Hello, I have been PCCN certified since 3/2020 with 9 years of stepdown and telemetry experience. I am happily transitioning this Summer to the ICU, and as a result I would eventually want to earn my CCRN. I have no interest in renewing my PCCN certification in 2023 and would like to attempt the CCRN at that time (I would be at about 2 years experience in the ICU by then). 

My questions are:

(1) Do I have to worry about completing the 100 hours of CE required for renewing the PCCN? I assume this is a no since the alternative is to retake the test.

(2) At this time my credentials are BSN, RN, PCCN. May I drop the "PCCN" once I allow it to lapse and have earned CCRN? I am not interested in carrying both PCCN and CCRN credentials. I would like to move forward in my nursing career dedicated to critical care. 

I feel like the answers to these questions are obvious so I feel kind of dumb asking, but I wanted to ask anyway. Thanks in advance for your replies!
