Yes. But even if you don't have the original certificate signing request
(CSR), you can generate it from the
existing certificate:

openssl x509 -x509toreq -in  ORIGINAL_CA_CERT -signkey PRIVATE_KEY -out
careq.csr

You could publish the renewed certificate and notify relying parties
about certificate renewal - probably it requires less labour.

However, if your CA root certificate is expiring soon, isn't it better
idea to do a re-key (of course, if it is allowed by your policy) than to
continue to use the old key-pair? (It is safer to do re-key time to time
than use the same key-pair for  a long period)
