IS this the way to go right? i mean, i dont need to buy any license if i
already got it from the old clearpass if im just using the second clearpass
for the HA right?
In 6.7 licensing in a cluster is a bit different for Policy manager
licenses which are now Access Licenses , prior to 6.7 if you had a node
with 500 licenses those weren't share across the cluster but in 6.7 Access
Licenses are shared across all nodes.
So if you decide to add more nodes (HW or Virtual) for redundancy /
capacity to the cluster you don't need to purchase additional licensing
