Sto provando ad utilizzare il prodotto StarWind per spostare delle VM native di un tenant ferso un altro tenant dentro una soluzione AVS.
Dopo aver creato nel source un Application ID/Secret e aver indicato come target il vCenter AVS utilizzando l'utenza "cloudadmin" messa a disposizione da Azure , quando scelgo l'host ESX il prodotto va in crash.
Ho installato StarWind dentro un jumbox azure nella network JumphostSubnet in modo tale che potesse comunicare con gli ESX.

Cosa manca in crash Starwind ?

Please let me know
-Source (where the VM is converted from; Hypervisor, version)
-What (What the VM is converted, hardware version can be helpful; disk type, interface type (e.g., VMXNET3, E1000E)
-Destination (where the VM is converted to: Hypervisor, version)

For cloud conversions, please let me know which public cloud you use.

I am trying to migrate native Azure VMs from Tenant A to Tenant B. In Tenant B, the target environment is an Azure VMware Solution (AVS) cluster with vSAN storage.
As a troubleshooting step, I also tested a different destination environment: an on-premises VMware infrastructure running vSphere/ESXi 6.7.
However, StarWind crashes at exactly the same point in both scenarios: when I select the destination ESXi host.
This suggests that the issue is not specific to AVS, vSAN, or the target environment itself, since the same behavior occurs against a completely different VMware platform.

Source:

Microsoft Azure native Virtual Machine on "tenantA"
Operating System: Windows Server 2019
VM Generation: Gen2 (UEFI/GPT)
Source hypervisor: Microsoft Hyper-V (Azure platform)

-Destination1:

CLOUD AZURE DIFFERENT TENANT "tenantB"
Azure VMware Solution (AVS)
VMware vSphere environment hosted in Azure
vSphere Client version 8.0.3.00500
VMware ESXi, 8.0.3, 24797835
Storage vSAN

OR:

-Destination2:

ONPREM site
VMWare 6.7
vSphere Client version 6.7.0.53000
VMware ESXi, 6.7.0, 24514018


Starwind crash on the same point when select the ESX destination

After many attempts targeting the on-premises site running VMware 6.7, I managed to start a conversion; here is the log:

Hi,

My colleagues mentioned that 6.7 is EOL, so they stopped further testing for it. They suggested trying the older version: https://starwind.my.salesforce.com/sfc/ ... ZfRIEODWXI
