Hi @rajsingh68,

When you say renewing certificate, does it mean you already have it on FTD (and re-using keys)? Or you renewed it with your public CA, and  you need to replace it in FTD as well (new keys)?

If it is with new keys, you'll need to create new PKCS12 file (which will contain cert chain, your cert and your private key), and then to import it to FTD. You can find guide here.

BR,
