  • Upgrade Your Cluster

MongoDB Realm allows you to upgrade your shared tier cluster (M0, M2, and M5) to a dedicated cluster. Upgrade your cluster before releasing a Realm Sync application by completing the following steps.


Using a shared tier cluster on a production application is not recommended. To avoid data loss, upgrade to a dedicated tier cluster before releasing your application.


Before upgrading your cluster, end any client application's Sync Connection. To do this, shut down all emulators, simulators, and terminals that are running your realm application.


To terminate Realm Sync, follow the instructions for Terminating Realm Sync.


Click the Upgrade green button under the Enhance Your Experience heading of the Atlas tab.
