We implemented the ClearPass VA-5K and thinking about failover, we installed another VA-5K to be the standby publisher. All is well but if we try to activate the standby publisher, it fails saying we need to use a different subscription ID. What is protocol on setting up the failover? Currently, the License Summary shows 10,000 for our total count, shouldn't it be 5000 if we're using it as a failover and don't need more than 5,000 devices? What am I missing here?
