All versions of Venafi
You've imported a number of certificates to the Trust Protection Platform from Digicert. At renewal, to ensure no down time, you renew before the cert has actually expired.
The new certificate issued from Digicert should append the remaining time from the original certificate to the new term.
The new certificate has only a single term length - the remaining time is lost.
The cause, essentially, is that Digicert doesn't recognize this as a renewal - they see it as a request for a new Certificate. Why? Because Venafi doesn't have the original Digicert ORDER_ID for the cert, and therefore doesn't recognize it when sent for renewal from Venafi. Instead, they simply send out a new one.
There are two possible scenarios:
1) Renew with Venafi and loose the remaining term - the first time only. After that, the now "new" certificate comes from Digicert with the Order_ID, and Venafi knows about it and tracks it for the next renewals moving forward.
2) Check Digicert for the Order_ID and add it to the Certificate in Venafi via a support tab edit. In the case of having several, Digicert may even send you a list of certificates and Order_ID's, but we can not confirm that at this time. For sure though, you can go to digicert, check the certificate, and claim the Order_ID from them.
**Additional Note** the Venafi support tab entry for the digicert order id is: Digicert CA:Request ID
For Option 2, would creating a custom field in Venafi with the Order_ID suffice? Can you go more in depth when you say "Check Digicert for the Order_ID and add it to the Certificate in Venafi".
