Note
Before starting the downgrade process, take a snapshot of the traffic flowing through the router and use
it as a benchmark to compare against traffic flow during the downgrade and/or after completing the
downgrade. Since it is a hitless downgrade, there should be zero impact to the traffic flow during the
downgrade and/or after completing the downgrade.
