You can manually restart an instance when the number of connections exceeds the threshold or any performance issue occurs for the instance. However, when an instance is restarted, it automatically performs a minor upgrade (for example, from MySQL 5.6.1 to MySQL 5.6.2). The updated version may have incompatibility issues, and can render your services unavailable. Therefore, before you restart an instance, we recommend that you first purchase a new instance to test its compatibility. You can restart the old instance only after testing the compatibility of the instance. Furthermore, restarting an instance may interrupt connections. Proceed with caution and make appropriate service arrangements before restarting an instance.
