    Hello, client certificate repository is syncronized in a HA cluster so if you need to renew client certificate you can just do it on one unit and then perform config sync. Usually, import new key first and then import new certificate. If you're creating a new object, you will also need to modify clientSSL profiles and refer the new certificate/key pair and eventually new trust chain as well.

    Hello,

    Sorry, I though he was asking about the device certificate itself. For the client ceritificate for any service, it can be synced betwen the HA pair as CA_Valli mentioned.

Hello,

I think you should renew the certificate on each appliance as they are expiring. Also, each device certificate is linked with the device hostname so i think each certificate should be renewed.

Then, you can sync the datasync-global-dg and device_trust_group.
