Renew a certificate

[4212Billy]

My secure certificates have expired. How do I create and install new ones that will last a whole year instead of three months?
I know I've seen this topic before, but I have searched the forums for about 45 minutes now and can't find them. Sorry if it's been discussed to death, but can someone point me to the right place???
Thanks!

sorry for lame question
i have to renew a ssl commercial certificate, as it very near to expire (between 10 days)

this is a rapidssl cert and i apply for it using onlinenic form

now, i am in this form and it ask me if it is an *initial* cert or a *renewal* one, indeed i select a renewal
then, it ask me for a csr, my question is:

can i submit the same csr i used one year ago or should i recreate a new csr?
i think that i should use the older csr, but i would be sure to do the right things before proceed
tia for any help
