If you have a problem with the current certificate, or if your corporate security policy requires doing so, you can replace default vCenter ServerHeartbeat certificates.
Install OpenSSL on the system where you intend to replace the certificate.
Obtain the certificate files rui.crt, rui.key, and rui.pfx.
- Download the SSLImport.jar utility from the VMware Knowledge Base article Replacing SSL Certificates for vCenter Server Heartbeat 6.x (KB 2013041).
- Follow the steps in the knowledge base article to replace the certificate.
