    SAP CCtr is using Windows APIs to handle certificates and therefore there should be no effect if you change the user certificates from SHA1 to SHA2. Check anyhow that your server OS version supports SHA2. SAP even recommend to use SHA2 level certificates in the application. Therefore I recommend to check what level certificates the application is using.

    If there is changes in certificate common name or CA name then it will require configuration changes at System Configurator - user settings.

    As always this kind of changes are recommended to be checked in quality/test environment before taking to prod. Also I would consider checking CCtr version and if older than SP10 then recommendation is to upgrade. Latest release is FP14. List of available release can be checked from example here:

    Note that even the SP10 is already out of maintenance and no corrections are provided for the version. Details about CCtr maintenance can be read from note 2655046.
