MongoDB Cluster-to-Cluster Sync (original) (raw)

Migrate your cluster anywhere you want to run it

MongoDB gives you the flexibility to run anywhere and Cluster-to-Cluster Sync helps you move your data there. You can easily migrate your databases that are on-premises, in a private cloud, hybrid cloud, or public cloud with minimal downtime.

Get more control over your migrations

Cluster-to-Cluster Sync gives you more options like migrating between different versions of MongoDB and migrating from a replica set to a sharded cluster.

Less downtime, more successful migrations

Your original cluster keeps working while the migration takes place. Easily resume synchronization in case of interruptions. An embedded verifier makes sure all your data is correct before you perform the cutover to the new cluster.
