Renewing drivers license without the notification postcard?

I forgot to change the address on my drivers license when I moved over a year ago. I plan on going to update it today, however, the expiration date on my DL is for April 16th. I'm afraid that the renewal notification has already been sent to my old address and probably lost. Is it possible to have it reissued? Is it actually required to update my license or can I just do a web reservation and go get it renewed? I did register my new address with JP Post after I moved, but I am not sure if that means that all my mail will be automatically forwarded to me.
