[mohammed.enab]

Hi,

I've a ready and wroking setup for Cisco NAC and i need to upgrade it to the new ISE, other than dot1x changes n the switches configurations, what else will need to be configured

does the upgrade makes it a fresh installation?

Yes, the NAC portion in ISE looks totally different from NAC since it's now working over Radius.

So I suggest you build a new setup with ISE in parrallel with your current production environment and test your config before doing the switchover.
