SAP Mobile Platform Server includes a default self-signed certificate. You must change this default certificate with a production-ready certificate after you install SAP Mobile Platform. For shared certificates, SAP recommends that you maintain the existing certificate alias when importing the new certificates. Then, when you replace the default certificate with the new production certificate, you are updating change the certificate for all listeners simultaneously.
SAP Mobile Platform Server and Management Cockpit share the same keystore (that is, <SMP_HOME>\Server\configuration\smp_keystore.jks).
