XDA’s home-lab column keeps pointing at a truth that Proxmox users learn the hard way: the built-in qm migrate command is fine for moving a VM inside a cluster, but every other migration path (bringing a VMware VM in, moving a Windows guest between clusters, evacuating a node for maintenance) needs a real tool. In 2026 the shortlist is small but strong, spanning free open-source utilities and paid enterprise migration suites. We tested eight desktop apps for Proxmox VM migration to see which ones actually save you hours instead of adding new failure modes.
What to look for in a Proxmox migration tool
Migration is where you find out how honest a hypervisor’s marketing was. The tools that hold up share these traits:
- Live migration support. Moving a running VM between nodes without powering it off is the difference between a scheduled maintenance window and a Sunday afternoon lost.
- Cross-hypervisor conversion. VMware VMDK, Hyper-V VHDX, and OVA appliances all need to become qcow2 or raw before Proxmox will boot them.
- Storage-agnostic operation. Some tools assume shared storage (Ceph, NFS); others work with local ZFS pools. Match to your setup.
- Load balancing across a cluster. Migrating one VM is easy. Rebalancing dozens across three nodes based on live CPU and memory metrics is the harder problem.
- Rollback on failure. A migration that half-succeeds and leaves a phantom disk on the target node is worse than one that refuses to start. Real tools track state and clean up.
- Windows VirtIO driver support. Windows guests will boot to a blue screen on Proxmox without the right virtio storage drivers baked in first. Tools that automate this step save real time.

The apps
1. Proxmox VE built-in migrate, best for same-cluster moves
Proxmox VE built-in migrate is what you should reach for 80% of the time. qm migrate (for VMs) and pct migrate (for containers) handle live migration across cluster nodes over the corosync network. Since Proxmox VE 8.0, qm remote-migrate also handles moves between separate clusters over SSH, which used to require a full backup-and-restore cycle. Storage migration between local disks, ZFS, Ceph, and NFS works transparently.
Where it falls short: Only migrates between Proxmox nodes. No cross-hypervisor support. Live migration requires shared storage or the newer local-storage live migration mode, which is slower on large VMs.
Pricing: Included with Proxmox VE. The optional Enterprise repository requires a subscription starting at around €115/year per socket.
Platforms: Linux (Proxmox VE host).
Download: Proxmox.com/downloads
Bottom line: Start here for every same-cluster or cluster-to-cluster Proxmox move.
2. ProxLB, best for continuous rebalancing
ProxLB is the “overkill for a home lab” tool XDA highlighted recently, and it earns the label. It watches CPU, memory, disk, and network metrics across every node in a Proxmox cluster and live-migrates VMs to balance the load automatically, in the background, without you touching a shell. Fine-grained affinity and anti-affinity rules keep specific workloads pinned or apart. Runs as a systemd service on any node.
Where it falls short: Not part of official Proxmox. Community-supported, so treat it accordingly. Overhead of live migration during business hours can spike network use if you have hundreds of VMs.
Pricing: Free, open source (GPL).
Platforms: Linux (runs on the Proxmox host or a management node).
Download: GitHub.com/gyptazy/ProxLB
Bottom line: Install this the day your cluster grows past two nodes. You will not go back.
3. StarWind V2V Converter, best for VMware to Proxmox
StarWind V2V Converter is the fastest, most reliable free tool for converting VMware VMDK and Hyper-V VHDX images into Proxmox-compatible raw or qcow2 disks. Runs on a Windows workstation, mounts the source image, streams the converted disk directly onto the Proxmox host over SSH, and handles the VirtIO driver injection for Windows guests during the same pass.
Where it falls short: Windows-only GUI. If your workflow lives on Linux, you’ll want qemu-img convert and virt-v2v instead. Registration required for download.
Pricing: Free (registration required).
Platforms: Windows.
Download: StarWindSoftware.com/v2v-converter
Bottom line: The clean answer if you’re bringing VMware VMs into a fresh Proxmox cluster and prefer a GUI.
4. VMware vCenter Converter, best for physical-to-virtual
VMware vCenter Converter does one thing well: turn a running Windows or Linux physical machine into a virtual disk image. You then convert that image (Clonezilla, StarWind, or qemu-img) into a Proxmox VM. Awkward two-step, but the P2V step itself is more reliable than any current open-source alternative.
Where it falls short: VMware suspended new development for years and only recently resumed. The output format is VMDK, so you always need a second conversion pass to land on Proxmox. Requires a free Broadcom Support Portal account.
Pricing: Free (Broadcom account required).
Platforms: Windows.
Download: Broadcom.com/products/vmware-vcenter-converter
Bottom line: Reach for this specifically when you’re virtualizing a physical machine that will land on Proxmox.
5. Clonezilla, best free bare-metal imager
Clonezilla Live is the open-source imaging tool the home-lab community keeps returning to. Boot the target physical machine from a Clonezilla USB, image the disk to a network share, then restore into a fresh Proxmox VM with the right virtio disk. Slower than the dedicated V2V tools but with zero licensing friction and full control over the process.
Where it falls short: No hypervisor awareness at all. You handle every step manually, including installing virtio drivers on Windows guests before the first boot in Proxmox.
Pricing: Free, open source (GPL).
Platforms: Linux (bootable Live image).
Download: Clonezilla.org
Bottom line: The right choice when you don’t want to install anything permanent on the source or the target.
6. Veeam Backup & Replication Community, best backup-based migration
Veeam Backup & Replication Community Edition now includes native Proxmox as both a source and a target since version 12.3, which turns any backed-up VMware or Hyper-V VM into a restore-to-Proxmox operation with a few clicks. Instant recovery brings the VM online on the Proxmox side while the full restore streams in the background.
Where it falls short: Free edition caps at 10 protected workloads. Above that you’re on paid Veeam licensing, which is far from cheap. Windows-only management console.
Pricing: Free for up to 10 workloads. Paid tiers scale from there.
Platforms: Windows (management console); backups work across all supported hypervisors.
Download: Veeam.com/community-edition-download
Bottom line: Ideal for small businesses moving off VMware after the Broadcom pricing shakeup.
7. Proxmox Backup Server, best same-brand backup workflow
Proxmox Backup Server paired with a Proxmox VE cluster provides deduplicated, incremental backups that double as a migration mechanism: back up a VM on cluster A, restore it on cluster B, done. Since PBS 3, restore is fast enough that this pattern competes with qm remote-migrate for cross-cluster moves that need a longer transfer window (WAN, slow disks).
Where it falls short: Adds another daemon to run and monitor. Meaningless if you only run one cluster.
Pricing: Free, open source. Enterprise subscription optional.
Platforms: Linux.
Download: Proxmox.com/downloads
Bottom line: The natural companion for anyone standardizing on Proxmox end to end.
8. Vinchin Backup & Recovery, best enterprise V2V
Vinchin Backup & Recovery is the paid option to consider when the migration is cross-hypervisor at scale (VMware to Proxmox, Hyper-V to Proxmox, or the reverse) and you want a supported product rather than a chain of open-source tools. Includes deduplication, encryption, and application-consistent snapshots for databases like Oracle and SQL Server.
Where it falls short: Not cheap once you scale past the trial. Overkill for a home lab. The UI has a distinctly enterprise feel that some admins find dated.
Pricing: 60-day free trial; paid pricing quoted per socket via sales.
Platforms: Linux, Windows.
Download: Vinchin.com
Bottom line: The commercial pick when you need vendor support for a big cross-hypervisor migration project.

FAQ
Can Proxmox migrate a VM without downtime?
Yes. Live migration inside a cluster runs on qm migrate <vmid> <target-node> --online. Shared storage is preferred, but Proxmox 8 supports live migration between local disks as well, at a slower transfer rate.
How do I move a VM between separate Proxmox clusters?
Use qm remote-migrate (available since Proxmox VE 8.0) for an SSH-tunneled transfer. If your network makes the direct transfer impractical, back the VM up with Proxmox Backup Server on cluster A and restore it on cluster B.
What is the easiest way to convert a VMware VMDK to Proxmox?
For a single VM, qemu-img convert -f vmdk -O qcow2 source.vmdk dest.qcow2 on the Proxmox host. For a Windows VM at scale, StarWind V2V Converter or virt-v2v handle both the disk conversion and the VirtIO driver injection in one pass.
Do I need virtio drivers for Windows guests?
Yes. Windows guests will not boot on Proxmox with a virtio-scsi controller unless the driver is loaded first. Attach the virtio-win ISO before boot, or use virt-v2v / StarWind, which handle this automatically.
Is ProxLB safe to run in production?
Home labs and small businesses use ProxLB comfortably, and the project has been stable for several release cycles. Community-supported rather than official Proxmox software, so plan a maintenance window before the first install and understand its migration policies before rolling out cluster-wide.
What replaces vCenter Converter for macOS admins?
Nothing that runs natively on macOS today. Either run vCenter Converter in a Windows VM, or use qemu-img + virt-v2v on a Linux workstation to handle the same job with a scriptable pipeline.
