Bulk/Mass converting VMWare to HyperV

[User1234]

Hello All,

I would like to mass convert VMs from vmware to hyperv and I've seen some replies about this feature is being worked on. However those replies were from several months ago. Is there an update on this?

I have tried doing this via CLI but keep running into issues

Also, if the host is in a cluster with DRS/HA enabled, then this feature needs to be disabled before running this correct?

I've noticed a typo. in-host_type needs to be redone as in_host_type
Can you please share the exact line you use? Feel free to replace ips and passwords with something else.

Good eye, I have corrected it and am still receiving the same error though

script:
V2V_ConverterConsole.exe convert in_host_type=esx in_host_address="ip address" in_host_username="vcenter local admin" in_host_password="vcenter admin password" in_vm_name="name of vm" out_host_type=win out_host_address="name of hyperv host" out_host_username="local admin account on hyperv host" out_host_password="password of local admin" out_vm_name="name of vm" out_file_name="C:\Test VMs\disk1.vhdx" out_file_type="ft_vhdx_growable"

Sorry for the misunderstanding.
CLI-based VM conversion is to be available in the upcoming build, not now. It should be there very soon.
Stay tuned
