Zimbra SSL update

Hello, I’m running the certificate term. Installed on the mail server Zimbra, how do I update it?

Can you please provide a little more information ?

How did you install it ? where you using the official client, or one of the alternates ?

What commands did you use ( exactly ) to create and install the certificate in the first place ?

I use manual from zimbra:
