Has anyone had experience with renewing their Admin Certificate on an ISE 2.6 distributed deployment ?
We currently have a 12 node deployment and the Admin Cert has just expired. We need to renew the Cert and was wondering about the impact of doing this? Will every node restart its services?
Also what procedure did you follow when you renewed the Certificate and generated the CSR? Did you generate a CSR for each node at a time and can all the details in the CSR be the same?
Depends on how many node deployment is this.
if 2 nodes you update on secondary node and promote to primary
then primary (become secondary, ) and update the cert other node.
So less impacts.
