Because peering configuration is not replicated, if you peer one of the clusters in the MetroCluster configuration to a third cluster outside of that configuration, you must also configure the peering on the partner MetroCluster cluster. This ensures peering can be maintained in the event of a switchover.
The non-MetroCluster cluster must be running Data ONTAP 8.3 or peering will be lost in the event of a switchover.
