You may need to update the security certificate in the following situations:
You restore a previous security certificate that the clients already use.
You want to use a different security certificate than the default certificate (.JKS).
When clients use secure communication with the server, the server certificate is exchanged between the server and the clients. This exchange establishes a trust relationship between the server and clients. When the certificate changes on the server, the trust relationship is broken and clients no longer can communicate. This problem is called orphaning clients.
Use this process to update either one management server or multiple management servers at the same time.
