title: Renew certificate with Java Keytool - reuse old CSR?
body: <p>I have an SSL certificate in a Java keystore.  It's going to expire in a week or so and I need to renew it.</p>
  
  <p>Can I reuse the previous CSR (which the CA still have) and then import the certificate using the <code>import</code> command or do I need to generate a new CSR?</p>
