-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 options 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. 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.
