How to setup storage migration from standalone Hyper-V host to Hyper-V failover cluster

Hi,

We have several standalone Intel-based Hyper-V hosts running W2019 and a new 2-node AMD-based Hyper-V cluster running W2025.

All hosts have full connectivity over a common high-speed management network and are also members of the same domain.

When trying to initiate a storage migration of a VM on the W2019 host to the new cluster we always get the "General access denied error' (0x80070005)"

We are targeting the active node on the cluster and have full access to the CSV when creating and selecting a folder.

Your insights would be greatly appreciated.

    Hi Sir，

    Thank you for contacting the Microsoft Community!

    We’ve noted that you’re experiencing an issue migrating from Hyper-V to a cluster.

    First, we do not recommend migrating virtual machines (VMs) from an Intel host to an AMD host, as this may cause the VM to fail to start or lead to compatibility issues.

    Next, let’s analyze your migration issue. You can refer to the following link: https://vmorecloud.com/step-by-step-hyper-v-storage-live-migration/

    1. Ensure that you are using an account with the necessary permissions to perform this operation.
    2. You can also try executing the migration using the following command:

    Move-VMStorage -VMName "VM NAME" -DestinationStoragePath "DESTINATION DATASTORE"

    1. Alternatively, you can shut down the VM, simply copy the files to the new location, and modify the VM configuration file to point to the new location.

    We hope the above information is helpful to you!

    Best Regards,

    Andrew
