<p class="MsoNormal">Both Expressway servers are signed by the internal CA. I have uploaded the root and intermediate certificates, too.<o:p></o:p></p>
<p class="MsoNormal">But I am renewing the certificates on an existing cluster, and whoever instelled it, they manually added the ExpC certs into tomcat-trust.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So, I understand that it would be safe to remove the ExpC certs from tomcat-trust and everything would be working fine?<o:p></o:p></p>
<p class="MsoNormal">What about the use the cluster name/don´t use the cluster name contradiction?<o:p></o:p></p>

<p class="MsoNormal">Are the expressway-C server using self-signed certificates (I doubt it because you said they are multi-san)?

<p class="MsoNormal">Generally, CUCM doesn’t need to trust the identity certificate (unless it is self signed). In all other cases, CUCM needs to trust the certificate authority the signed the expressway-c certificates.<o:p></o:p></p>
