How to I renew a new domain certificate and prevent down time when the old cert. expired?

[winnie_leung]

Dear Gurus,

We are doing implementation on ServiceNow and using the SAML 2.0 external authentication from Windows AD. Currently, the certificate is uploaded in the Certificate session and the system is up and running. However, as the certificate will expire one year later and no one will be able to logon after the certificate expired. Is there any way I can upload the new certificate before the old one expired? Looks like there can only be one certificate entry? And if the old certificate expired, users can no longer login to the system, how do we renew the certificate in ServiceNow? Thanks!

Best Regards,

Winnie

Thanks Bhavesh. Sorry that I am not very familiar with the keytool. Does it mean it can expand the certificate to valid beyond the original time as the certificate was generated? Thanks.

I have personally not tried but the author of that post seems to have done that.
