My single-domain standard SSL cert is going to expire. I intend to buy from GoDaddy this time as the price is only US$12.99/year.

1) Should I generate a new CSR for GoDaddy SSL cert or should I use the existing one?

2) If I generate a new CSR, will it cause my existing SSL cert to fail. It still has one month validity.

Sorry for this dummy questions.
