I assume you mean the portal/gateway server certificate is expiring.  You should be able to go to Device > Certificates > Import.  From there you can select "Encrypted Private Key and Certificate (PCKS12) from the File Format drop-down menu.  You'll need the password used by the sysadmin to encrypt the certificate as well.  

Once you've imported the new certificate, you'll want to go to Device > SSL/TLS Service Profile, open whichever SSL/TLS profile is used on your GlobalProtect gateway/portal, and select your new cert in the certificate drop-down.

Personally, I would wait to revoke the other certificate until you have the new certificate imported and tested, just in case you have to roll back your changes, but that's just my opinion.  If you go this route, you'll need to give them different names.  You can rename the old one, or give the new one a different name like MyCompanyName-2020-2021 for the dates the certificate is valid.  Whatever you want, just so they are different.

Yes, I have password for cert. Thanks Owen. You are so helpful.

@OwenFuller My existing cert name is 'MyCompanyName'. I want to use same name 'MyCompanyName' for new cert, so do I need to revoke  old 'MyCompanyName' cert first and then import the new cert with same name? I have scheduled maintenance window.
