How do I extend the expiration day of the self generated CA certificate andall the certs issued by t

We have created our own CA certificate and signed few more certs using it.
The CA is about to expire and with that all the certificates signed using
it. Is there a way to extend the expiration day with out recreating the CA
and reissuing the certs?
Please help
Thanks in advance.
