+If your database engine is outdated, you can upgrade the version to the latest one anytime via the Scaleway console.
+
+You must upgrade your engine version if your Database Instance uses an End of Life engine version that is no longer maintained.
+
+<Message type="important">
+The version upgrade is only available for Database Instances using engine versions preceding the most recent version available.

+- A Scaleway account logged into the [console](https://console.scaleway.com)
+- [Owner](/iam/concepts/#owner) status or [IAM permissions](/iam/concepts/#permission) allowing you to perform actions in the intended Organization

+
+1. Under **Databases** on the side menu, click **MongoDB**. A list of your Database Instances appears.
+2. Select the geographical region of the Instance you want to manage from the drop-down.
+3. Click the name of the database whose engine you want to upgrade. The Database Instance information page appears.
+4. Under **Database engine**, click **Upgrade**. A pop-up appears.
+5. Select the new version to which you want to upgrade.<br/>
+    The upgrade will create a new Instance with a public endpoint by default. The client will need to configure new endpoints on the new Instance and redirect their application to these new endpoints.
+
+    <Message type="important">
+      When you upgrade to a new version, there is no synchronization between the source and target Database Instances. To avoid data loss, we recommend you stop all write operations on your applications during the upgrade. If you let them run during the process, data will only be stored in the source Database Instance.
+    </Message>
+
+6. Click **Upgrade version**. A new Database Instance is created.
