Cluster-to-Cluster Sync

Cluster-to-Cluster Sync provides continuous data synchronization or a one-time data migration between two MongoDB clusters. You can enable Cluster-to-Cluster Sync with the mongosync utility.

mongosync can continuously synchronize data between two clusters. You can use mongosync to create dedicated analytics, development, or testing clusters that mirror your production environment. Synchronized clusters can also support locality requirements for audit and data residency compliance.

In addition to continuous data synchronization, mongosync can also facilitate a one time data migration between clusters.
