Expressway Server Certificate soon to expire

[Pointbreak]

The Server Certificate of Expressway E and and C are soon to expire. I presume the method is to generate CSR, download CSR , get it signed by CA and upload it . And reboot the Expressway?

I got 2 servers in expressway cluster. And i presume the new trust certificate will show up in the CUCM cluster too

AFAIK the Expressway certificates wouldn't show up in CUCM trust store.

Where did you read/hear that the certificate(s) you install on one product, would automagically be distributed to other products?

The answer is NO, it will not just show up in any other product without someone uploading either the server certificate or the root CA certificate to the relevant trust store.
