Version 1.1 Released January 13, 2023
Cluster-to-Cluster Sync provides continuous data synchronization or a one-time data migration between two MongoDB clusters. You can use filtered sync to specify which databases and collections the mongosync utility transfers between the source and destination clusters.
For more information, see: Filtered Sync.
Cluster-to-Cluster Sync 1.1 supports sync between clusters with different sharding configurations.
You can sync:
Between two sharded clusters
Between two sharded clusters with a different number of shards in each cluster
From a replica set to a sharded cluster
You cannot sync from a sharded cluster to a replica set.
For more information, see: Sharding Parameters.
Cluster-to-Cluster Sync requires at least MongoDB server version 6.0.4 on both the source and target clusters.
