OT: Renew a self signed cert that has expired

Hello experts:

I have a self signed certificate that establishes ssh/vpn connections. It
has expired. I am not looking to regenerate but hopefully extend existing is
this possible? How can it be done from CLI?

377555: Aug 15 10:19:49.942 PDT: %PKI-3-CERTIFICATE_INVALID_EXPIRED:
Certificate chain validation has failed. The certificate (SN: XXXX) has
expired. Validity period ended on 14:54:27 PDT Aug 12 2011

Thanks in advance for your help.
