One of our Servers SSL Certificates Public Key has recently expired.

Using C1 Version 1.3.6 h It seems that you can change the expiry dates for the public key through C1. (currently 2 years)

Will this solve our Server Certificate Expiry problem or do I need to re-create the entire certificate?

If I do edit through C1 will any services that use that certificate need to be re-assigned?

I want to do this in the least invasive way possible as the configuration was not deveoped by myself and I am trying not to brake the system.

Any input appreciated.
