https://www.nutanix.dev/reference/prism_central/v3/api/vms/postvmsuuidmigratedisks/ describes an API to migrate disks as vms/{uuid}/migrate_disks.  But the API is not available in AOS 6.0.  I got the following response

{ 

    "message": "The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again." 

} 

The swagger definition from the cluster does not contain the endpoint either even thought the definition “migrate_disk_input” is defined.

The cluster has the following information:

            "config": {

                "software_map": {

                    }   

                },
