     questions:
     - question: |
          Is message persistence supported?
-      answer: At Azure IoT Operations general availability (GA), full message persistence won't be supported. The capability is planned for post-GA.
+      answer: Currently, message persistence is not supported in the preview version of Azure IoT Operations.
     - question: |
          Does Azure IoT Operations offer high availability and zero data loss features at general availability?
-      answer: Azure IoT Operations workloads on K3s and HCI/Aks-Arc multi-node clusters should support distribution of Azure IoT Operations workloads across multi-nodes setups taking advantage of fault tolerance and Kubernetes scheduling of pods across nodes. The features are planned for general availability.
+      answer: Currently, Azure IoT Operations workloads on K3s and HCI/Aks-Arc multi-node clusters don't support distribution of Azure IoT Operations workloads across multi-nodes setups in the preview version.
     - question: |
          Can I migrate my IoT Edge workloads to Azure IoT Operations?
-      answer: Currently, there's no documented migration path from IoT Edge to Azure IoT Operations. However, some targeted migration is planned, so if you have any feature asks for Azure IoT Operations as part of any migration you're planning to do, we ask that you relay this back to us.

     - question: |
          Can I just upgrade my preview version to the general availability version?
       answer: You won't be able to upgrade from the preview to the general availability version directly. You'll need to redeploy.
     - question: |
          What Kubernetes distros are compatible with Azure IoT Operations?
       answer: Azure IoT Operations is only officially supported on two platforms now Ubuntu+K3s, Windows IoT + AKS EE. For more information, see [Prepare your Azure Arc-enabled Kubernetes cluster](../deploy-iot-ops/howto-prepare-cluster.md). 
     - question: |
-         For IoT Operations, which device communication protocols are going to be supported out-of-the-box in general availability?
-      answer: We have planned work to suppport more device communication protocoals in GA. However, for now we support OPC-UA and MQTT.
+         For IoT Operations, which device communication protocols supported.
+      answer: Currently in the preview version, we support OPC-UA and MQTT.
     - question: |
          Is there a non-Dapr Azure IoT Operations state store code example?
       answer: |
         Currently, we don't have an example/asset for external use. However, the StateStore documentation can help you understand how it can be used. For more information, see [MQTT broker state store protocol](../create-edge-apps/concept-about-state-store-protocol.md)
     - question: |
-         MQTT with QOS 2. Is this on the roadmap for IoT Operations MQ
-      answer: For Azure IoT Operations, it is on the roadmap. However, QoS 2 won't be supported in the initial Azure IoT Operations general availability.
+         Is MQTT with QoS 2 supported.
+      answer: Currently, QoS 2 is not supported.
     - question: |
          Which Azure regions is Azure IoT Operations currently available in?
       answer: Azure IoT Operations is available in East US2, West US 3, West Europe, East US, West US, West US 2, North Europe regions.
     - question: |
-         Is there a way to gracefully fail over between two redundant OPC UA servers in case one of them fails? The idea is to have minimal/zero data loss and no reconfiguration effort.
-      answer: Yes, we have this as a planned work for post-GA.
+         Is there a way to gracefully fail over between two redundant OPC UA servers in case one of them fails? 
+      answer: Currently, this is not supported in the preview version of Azure IoT Operations.
     - question: |
          Is there a hard limit on the sampling intervals for OPC UA tags for minimum and maximum sampling interval?
       answer: The minimum is 1ms, however there's no upper restriction imposed at the connector level
