Changing System Certificate to a new CA

[KatherineTran]

Hi Guys,

We are currently using a public ca signed certificate for DNA and need to use an internally signed CA certificate for PNP to add the SAN options. Will we need to reprovision or re-discover the devices we are monitoring for assurance when we do this? I noted in the documentation it could cause a problem but its not that clear.

Thank you

KT

Cisco DNA makes this very easy.  Once you upload the new certificate to Cisco DNA, it will push the necessary changes to all the devices it inventory.
