Can I use the same CSR more than once ?

You can reuse the same CSR and private key for certificate renewals. However, it's always a good practice to check with your specific CA or certificate provider to ensure their renewal process aligns with this approach.

I can confirm that I have been using the same CSR to renew my netscaler certificates for years now - the one thing to keep in mind is that you'll want to make sure that you're following current best practices on key length. If those best practices change; then you'll need to generate a new CSR to account for that.
