 For **Arc-enabled VMware vSphere**, manual upgrade and cloud upgrade are available. Appliances on version 1.0.15 and higher are automatically opted-in to cloud-managed upgrade. With cloud-managed upgrade, Microsoft may attempt to upgrade your Arc resource bridge at any time if it is on an appliance version that will soon be out of support. In order for either upgrade option to work, the upgrade prerequisites must be met. While Microsoft offers cloud-managed upgrade, you’re still responsible for checking that your resource bridge is healthy, online, in a "Running" status, and within the supported n-3 versions. Disruptions could cause cloud-managed upgrades to fail.  Any appliances that are earlier than version 1.0.15 must be manually upgraded. A manual upgrade only upgrades the appliance to the next version, not the latest version. If you have multiple versions to upgrade, another option is to review the steps for [performing a recovery](/azure/azure-arc/vmware-vsphere/recover-from-resource-bridge-deletion), then delete the appliance VM and perform the recovery steps. This deploys a new Arc resource bridge using the latest version and reconnects pre-existing Azure resources.
 
-For **Azure Arc VM management (preview) on Azure Stack HCI**, to use appliance version 1.0.15 or higher, you must be on Azure Stack HCI, version 23H2 (preview). In version 23H2 (preview), the LCM tool manages upgrades across all HCI, Arc resource bridge, and extension components as a "validated recipe" package. Attempting to upgrade Arc resource bridge independent of other HCI environment components by using the `az arcappliance upgrade` command may cause problems in your environment that could result in a disaster recovery scenario. For more information, visit the [Arc VM management FAQ page](/azure-stack/hci/manage/azure-arc-vms-faq). Customers on Azure Stack HCI, version 22H2 will receive limited support.

 For **Arc-enabled System Center Virtual Machine Manager (SCVMM)**, the manual upgrade feature is available for appliance version 1.0.14 and higher. Appliances below version 1.0.14 need to perform the recovery option to get to version 1.0.15 or higher. Review the steps for [performing the recovery operation](/azure/azure-arc/system-center-virtual-machine-manager/disaster-recovery), then delete the appliance VM from SCVMM and perform the recovery steps. This deploys a new resource bridge and reconnects pre-existing Azure resources.
