When setting up failover for a pair of DMAs using external Cassandra and OpenSearch clusters, do the Cassandra and OpenSearch database parameters (type, keyspace prefix, db server, user, password) need to be configured in advance on the backup member or the settings would be copied over automatically from the primary member during the failover configuration process?

Hi Laszlo,
The settings would be copied after the failover configuration.
But before that, you need to ensure the cassandra and opensearch nodes are reachable from the backup agent.
