VirtIO drivers on Windows
Injects the VirtIO drivers before the first boot, including the switch to the SCSI controller that Windows does not recognize on its own.
From VMware to Proxmox VE
MultiPortal Migrator: from VMware to Proxmox, with your VMs still running.
MultiPortal Migrator moves your virtual machines from VMware to Proxmox VE while they keep working: it copies the disks, keeps the changes in sync and switches over when you decide. We supply it, as Proxmox Gold Partner #1 in Italy.

Beyond copying the disks
What it does for you, VM by VM
Moving a VM from VMware to Proxmox means more than copying a disk: the virtual hardware under the operating system changes, and every forgotten detail is a machine that fails to boot. Migrator automates the steps you would otherwise repeat by hand for every VM.
Storage controller
Moves the disks from the default SATA controller to VirtIO SCSI, without the manual detour through Windows recovery mode.
Network and static IPs
Reconfigures the network adapters of every VM: static addresses survive the hardware change, and there is no need to open the console.
QEMU agent instead of VMware Tools
Installs the QEMU guest agent and removes VMware Tools, which have nothing left to talk to on Proxmox VE.
Windows and Linux in the same batch
Recognizes the operating system of every VM and applies the right preparation at cutover, even in a mixed batch.
Checks before you start
Verifies the environment before the migration and tells you at the planning stage whether the target storage supports the low-downtime modes.
How it works
Five phases, from discovery to a running VM on Proxmox
The Migrator appliance connects to VMware and to Proxmox VE and orchestrates every step. The source machine is not touched until the cutover.
VMware vSphere 8
vCenter Server or ESXi
Proxmox VE 9
Single node or cluster
The source VM stays intact until the cutover
-
Phase 02 You choose the VMs and where they go: Proxmox node, storage, disk format and networks. Nothing changes inside the guest system yet.
-
Phase 04 When you start it: final synchronization, source shutdown, drivers and network prepared, boot on Proxmox.
- 01 Discovery
- 02 Plan
- 03 Synchronization
- 04 Cutover
- 05 Completed
-
Phase 01 Migrator reads the VMs from vCenter or from an ESXi host, with their disks, networks and changed block tracking status.
-
Phase 03 The disks move to Proxmox while the VM keeps working, then only the changed blocks travel, for as long as you need.
-
Phase 05 The VM runs on Proxmox VE. The VMware VM stays powered off where it was, and the migration report goes into the history.
If something goes wrong after the source is shut down, Migrator discards the VM on Proxmox and powers the VMware VM back on.
One console
Every migration, phase by phase
Every VM is a job with its own status: preparation, transfer, synchronization, cutover. You see how much of each disk is already on Proxmox, when it started and when it finished, and you download the migration report in Excel or PDF.
- Migration batches with a result for every VM
- Up to 32 migrations in parallel
- Searchable history and reports in xlsx and pdf
Parallelism as stated by MultiPortal in the Migrator price list.
Three ways to copy
Continuous replication, hot or cold
You choose the mode VM by VM: it changes how long the machine stays off and what the environment needs.
Mode
Continuous (CBT)
Hot (snapshot)
Cold
Source VM during the copy
On
On during the base copy
Off for the whole copy
What is copied
The whole disk, then only the changed blocks, in cycles
The base disk, then the latest changes at cutover
The whole disk
VM downtime
The cutover alone, a few seconds
The time needed to apply the latest changes
The whole duration of the copy
What you need
VMware VDDK on the appliance, CBT enabled, a source license with CBT and VADP, target storage with snapshots
Storage with snapshots on source and target (not vSAN)
Nothing in particular: it works with every supported storage
Source: MultiPortal Migrator documentation. VDDK is the VMware library that reads the disks: Broadcom restricts its distribution, so you download it from the Broadcom portal and upload it to the appliance. Without VDDK, cold migration still works.
Continuous replication
Only the blocks that change travel
With VMware changed block tracking, after the first copy Migrator sends only the modified blocks to Proxmox, in cycles, until you start the cutover: even for days, if you need to. The result is a near-live migration from vSphere to Proxmox VE. In the vendor's test, a Debian 12 VM with a 40 GB disk transferred 2.8 GB in total, and the cutover took 10 seconds.
Security and rollback
You can always go back
Source intact until the cutover
The VMware VM keeps working, unchanged, until you start the cutover: that is the first moment Migrator touches it.
Automatic rollback
If something fails after the source is shut down, the VM on Proxmox is discarded and the VMware VM is powered back on: you are never left halfway between two machines.
Nothing is deleted
After a successful cutover the VMware VM stays powered off where it was. Going back means powering it on again.
Cleanup and history
Leftover migration snapshots are removed automatically, and the history records what happened, when and on which VMs.
What you need to get started
The Migrator appliance is a VM you install on your Proxmox VE: it contains the console, the database and the migration engine. The disks travel over SSH directly from the ESXi host to the Proxmox node, so credentials and data never leave your network; the appliance needs internet access only for license verification and downloads.
Windows VMs also need the VirtIO drivers ISO. Other versions of the same families, such as AlmaLinux or other Debian and Ubuntu releases, should work, but the vendor has not tested them yet.

License
License per VM, paid once
Migrator has its own license, separate from the MultiPortal platform: you pay once for every VM you move, and the license is valid for 12 months. Migrating the same VM again does not use another license. We base the quote on the number of VMs, and if you would rather not run the migration yourself, we design it and carry it out for you.
Included in the price
- All three migration modes
- Unlimited environment assessments
- Automatic preparation of Windows and Linux
- Migration report for every VM
- A price per VM that falls as the number of VMs grows

Frequently asked questions
What is MultiPortal Migrator?
MultiPortal Migrator is software that moves virtual machines from VMware vSphere, with vCenter Server or an ESXi host, to Proxmox VE. It runs as an appliance inside your infrastructure, copies the disks while the VMs keep working and automates drivers, storage controllers and networking. It is a product in its own right, with a license separate from the MultiPortal platform.
Which VMware to Proxmox migration tool should I use?
Proxmox VE has included a native ESXi importer since version 8.2, and for many environments it is enough. MultiPortal Migrator is the tool for when the VMs are many or cannot stop: it adds continuous replication with changed block tracking, parallel batches, automatic preparation of Windows and Linux, and rollback if the cutover fails.
How long is a VM down during a migration to Proxmox with Migrator?
It depends on the mode. With continuous replication the downtime is the cutover alone, a few seconds: in the lab test published by MultiPortal, 10 seconds for a Debian 12 VM with a 40 GB disk. In hot mode it is the time needed to apply the latest changes; in cold mode the VM stays off for the whole copy.
What happens to the VMware VM after a migration with Migrator?
The VMware VM stays where it is, powered off, and is not deleted. If something fails after the shutdown, MultiPortal Migrator discards the VM on Proxmox and powers the VMware VM back on; even after a successful cutover, going back means powering the source machine on again.
Which VMware and Proxmox versions does MultiPortal Migrator support?
MultiPortal Migrator supports VMware vSphere 8 as a source, with vCenter Server or a single ESXi host; the vendor has not yet tested versions 7 and 9. As a target it supports Proxmox VE 9.x, single node or cluster: earlier Proxmox VE versions are not supported.
What does continuous replication from VMware to Proxmox require?
Continuous replication with MultiPortal Migrator requires the VMware VDDK library uploaded to the appliance, changed block tracking enabled on the VM, a source license that includes CBT and VADP, and target storage with snapshots. You download VDDK yourself from the Broadcom portal, which restricts its distribution.
Does migration data pass through an external cloud?
No. The MultiPortal Migrator appliance runs on your Proxmox VE and the disks travel over SSH directly from the ESXi host to the Proxmox node: credentials and data never leave your network. The appliance goes online only for license verification and downloads.
How much does a MultiPortal Migrator license cost?
A MultiPortal Migrator license is paid once for every VM to migrate, in progressive tiers, VAT excluded: the first 5 VMs are free, then €27 per VM from the 6th to the 50th, €22 from the 51st to the 200th, €18 from the 201st to the 1,000th, and the price keeps falling down to €4 per VM above 50,000 VMs. The license is valid for 12 months, and migrating the same VM again costs nothing. Rackone applies its reserved pricing to this price list in the quote.
