+Scaleway Managed MongoDB® is compatible with the [MongoDB® Cluster-to-Cluster tool](https://www.mongodb.com/docs/cluster-to-cluster-sync/current/quickstart/#std-label-c2c-quickstart).
+
+Cluster-to-Cluster sync helps you migrate data from one cluster to another without downtime through synchronization. Until the sync is finalized, the tool replicates and writes data from one cluster to another.

+
+  - A Scaleway account logged into the [console](https://console.scaleway.com)
+  - A [MongoDB® Database Instance](/managed-mongodb-databases/how-to/create-a-database-instance/)
+  - Installed a [MongoDB®-compatible client](https://www.mongodb.com/try/download/shell)
+  - Set up your [environment variables](/scaleway-cli/reference-content/environment-variables/#reserved-environment-variables) for the Scaleway API
+
+1. Create a user in your MongoDB® Instance. Make sure you replace `<user-name>`, `<password>` and `{instance_id}` with the user name of the user, its password and the MongoDB® Instance UUID, respectively.
+
+    ```
+    curl -X POST \
+      -H "X-Auth-Token: $SCW_SECRET_KEY" \
+      -H "Content-Type: application/json" \
+      -d '{"name":"<user-name>","password":"<password>"}' \
+      "https://api.scaleway.com/mongodb/v1/regions/fr-par/instances/{instance_id}/users"
+    ```
+
+2. [Apply the `sync` role to the user](/managed-mongodb-databases/how-to/manage-users/#how-to-apply-a-role-to-a-user). The `db_admin`role also allows you to sync.
+3. [Download and install `mongosync` for your host system](https://www.mongodb.com/docs/cluster-to-cluster-sync/current/quickstart/#download-and-install-mongosync).
+
+    <Message type="tip">
+      If the database you want to sync is bigger than 100GB, we recommend you use a [Scaleway Instance](/instances/how-to/create-an-instance) to sync.
+    </Message>
+    ```
+3. [Connect the clusters](https://www.mongodb.com/docs/cluster-to-cluster-sync/current/quickstart/#connect-the-clusters).
+
+4. [Migrate data between clusters](https://www.mongodb.com/docs/cluster-to-cluster-sync/current/quickstart/#migrate-data-between-clusters).
+
+5. [Finalize the cut-over process](https://www.mongodb.com/docs/cluster-to-cluster-sync/current/quickstart/#finalize-cutover-process).
