You also don’t need to restart the TFTP service when regenerating TVS certs, in fact it can cause problems depending on how quickly you pull the trigger and how many phones you have.

<div class="">As soon as you regenerate TVS on any node, all phones will reboot and ITL will be updated instantly. Be very careful to do this one node at a time making sure all phones re-register before moving on. Really only a huge issue if you are doing
the CallManager.pem at the same time.</div>

<div class="">TVS certs aren't in the CTL last I checked so you shouldn't need to regenerate the CTL on mixed-mode clusters if just updating TVS/IPSec.</div>
