# MongoDB Atlas: scale a cluster's tier

## Steps
1. In Atlas, select the organization and project, then click Clusters under the Database heading.
2. For the cluster to modify, click the ⋮ (three-dot menu) and select Edit Configuration.
3. In the Cluster Tier section, select the new tier (can't scale below M10).
4. Click Review Changes to see current vs. new settings and any downtime/billing warnings.
5. Click Apply Changes.

## End state
Atlas reboots all nodes to apply the new tier; the cluster shows the new tier once the change completes (NVMe storage requires an initial sync).
