 Rolling updates can only occur if the MQTT broker is deployed with two or more backend replicas. MQTT broker upgrades aren't supported for single-replica deployments. When you deploy Azure IoT Operations, you specify the number of backend replicas to create in the [az iot ops create](/cli/azure/iot/ops#az-iot-ops-create) command with the `--broker-backend-rf` parameter.

+Microsoft always supports three generally available (GA) versions of Azure IoT Operations at any one time: the latest version, and the two previous minor versions.
+
+Currently, there are only two minor versions available. [Azure support](https://azure.microsoft.com/support/plans) is currently available for the following versions:
+
+- [1.1.x](https://github.com/Azure/azure-iot-operations/releases/tag/v1.1.19) (latest GA version)
+- [1.0.x](https://github.com/Azure/azure-iot-operations/releases/tag/v1.0.9) (previous minor GA version)
+
+> [!IMPORTANT]
+> Previous minor versions don't receive security patches. Always upgrade to the latest version to ensure you have the latest security updates and features.
+
+To verify your current version, see the overview page for your Azure IoT Operations instance in the Azure portal or use the Azure IoT Operations CLI [az iot ops instance show](/cli/azure/iot/ops#az-iot-ops-show) command.
