Aries other then Pasport photos and the application filled out and a check is their anything else needed for renewal?
Same app as filing for a new permit. Just mark renewal at the top, new photos within 30 days of filing for renewal. No references, finger prints or newspaper ad needed. (not yet).
At some point it all will change. Permits will be good for 3 years at first and then 5 years after every renewal. Price will go up based on yearly fee. Your CCDW permits will be webbed into your drivers license, no photos will be needed they will just use your drivers photos. (how and when all this will take place is a guessing game, no one has an answer)
Don't be surprised if you wake up some day and the DSP has full control over the CCDW process.
