Hi fsdg,
Hope you're doing well.
Migrating Hyper-V VMs between clusters can be done, even when the clusters are in different domains. Let's break down the process:
- Shared Nothing Live Migration:
This feature allows you to move VMs between clusters without shared storage. It's particularly useful when the clusters are in different domains.
(1) In Failover Cluster Manager, remove the Virtual Machine role for the VM you want to move from the original cluster.
(2) Use the native Hyper-V Manager to "move" the actual VMs to the new cluster. Both processes can be done while the VMs are running.
(3) Initiate the move from the source server. If needed, configure Kerberos authentication for live migration settings.
NOte: Test this process on non-production VMs first to ensure it works smoothly.
- You can also export VMs from one cluster and import them into another. Here's how:
(1) In Hyper-V Manager, right-click on the VM and choose "Export." This creates a VM export file.
(2) Copy the export file to the new cluster.
(3) In Hyper-V Manager on the new cluster, choose "Import Virtual Machine" and select the exported file.
(4) Follow the wizard to configure settings for the imported VM.
- Enabling live migration won't impact the host or the entire cluster. It only affects the VMs being moved. Live migration allows VMs to move between hosts without downtime. The source host remains operational. Ensure that both clusters have compatible hardware and network configurations for successful live migration.
