NAC - CAM & CAS Certificate renewal

Hi All,

We have CAM and CAS for guest users, both are in HA pair, we are in progress to migrate to ISE, but certificates are expiring soon in CAM and CAS so it requires renewal

We are using common name (mapped to Virtual IP) and generated certificates for CAM and CAS, as CA has raised its standard, we have to generate a new CSR for CAM and CAS 

 

Is it possible to generate CSR with same common name as earlier? We do not want to disturb the existing setup as its already end of support

Also will both CSR be on the devices with same common name? please suggest

 

Thanks
