The stock workflows shipped with the Community Edition do not distinguish 
between an initial manual certificate request and a certificate renewal. A 
manual certificate renewal looks exactly like the initial certificate request 
and must be processed in the same way.
However, the system implicitly tracks the underlying end entity by applying a 
(configurable) unique subject policy. During the manual request process, an 
indication is provided to the Registrations Officer which links to possibly 
existing certificates for the same subject, allowing to apply ample scrutiny on 
the request.

Certificate renewal for the automated interfaces EST, SCEP, RPC will issue 
exactly the same certificate that was initially requested (with updated 
validity and public key), regardless of the details in the certificate request. 
Unique subject constraints are enforced for automatic enrollments, and the 
system can be configured to either reject renewal requests outside the 
designated renewal window (e. g. 60 days before expiration) or to change into a 
"replacement" mode which is very similar to a certificate renewal (but outside 
the renewal window) but results in a replacement certificate with the SAME 
validity as the existing certificate. In addition the system can automatically 
create revocation request for the existing certificate scheduled for automatic 
execution in the future (effectively revoking the existing certificate after a 
grace period).

A manual renewal workflow which can act on an existing certificate is not 
shipped with the OpenXPKI Community Edition. If you require such a workflow, 
this is possible with the Enterprise Edition. In this case please get in touch 
with White Rabbit Security GmbH.

Cheers
