+      answer: Currently, message persistence isn't 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: 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-node 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. If you have any feature asks for Azure IoT Operations as part of your migration plans, relay your requests back to us.
+    - question: |
+         Can I just upgrade my preview version to the general availability version?
+      answer: You can't upgrade from the preview to the general availability version directly. You need to redeploy.
+    - question: |
+         What Kubernetes distributions are compatible with Azure IoT Operations?
+      answer: Azure IoT Operations is only officially supported on two platforms now Ubuntu using K3s, Windows IoT using AKS Edge Essentials. For more information, see [Prepare your Azure Arc-enabled Kubernetes cluster](../deploy-iot-ops/howto-prepare-cluster.md).
