Downgrading to Version 8.2 or earlier versions—Version 8.3 introduced more robust time-based key
usage as well as failover license changes:
– If you have more than one time-based activation key active, when you downgrade, only the most
recently activated time-based key can be active. Any other keys are made inactive.
– If you have mismatched licenses on a failover pair, then downgrading will disable failover. Even
if the keys are matching, the license used will no longer be a combined license.
