Pair Clusters for Replication
You must pair two clusters to communicate with one another before you can replicate data between the clusters. After the clusters are paired, you can create a replication policy, during which you establish which are the source and destination clusters in the replication relationship.
Prerequisites
Before pairing, clusters must have been enabled for use with Data Lifecycle Manager from the DPS Platform UI.
The clusters you want to pair must have symmetrical security configurations for Kerberos, LDAP, Ranger, Knox, HA, etc.
About This Task
You must be logged in with the DLM Infra Admin role to perform this task.

In the DLM navigation pane, click Pairings.
