What is VMware vCenter Converter?

VMware vCenter Converter is one of the most widely used tools for physical-to-virtual (P2V) and virtual-to-virtual (V2V) migrations in VMware environments. Whether you’re migrating legacy physical servers to VMware ESXi, consolidating workloads, or moving virtual machines from another platform, Converter simplifies the migration process with minimal downtime.

Is it free?

vCenter Converter is an official P2V and V2V converter, and it is free to download and use. But you should know that:

1. Download requires a registered account on the Broadcom Support Portal.

2. support entitlement, and downloadable versions may vary depending on your organization’s account status and VMware licensing agreements. Broadcom currently distributes Converter through its official software download portal.

Note: What is Converter, vSphere Converter, and Converter standalone?

These refer to the same tool: VMware vCenter Converter Standalone. It was called vSphere Converter, but the current official name is vCenter Converter Standalone. “Standalone” is to emphasize that this is an independently installed tool that does not require vCenter to run.

This guide explains what VMware vCenter Converter is, where to download it, how to install it safely, and how to perform both P2V and V2V migrations successfully.

Step 3. Choose the installation directory.

Step 4. Install Converter components.

Step 5. Launch VMware vCenter Converter Standalone.

Most administrators install Converter on a dedicated management workstation rather than directly on production servers.

Next, we will guide you how to use it to perform P2V or V2P conversion. It is suggested that to create a full system backup or VM backup for your source system, in case of any error.

How to Use VMware vCenter Converter for P2V, V2V Migration

Before installation, prepare the following:✎…
Firewalls permit communication between source and destination systems. 
Required VMware services and management ports are reachable.
Make sure the destination VM has enough datastore capacity and available CPU and memory resources.

P2V conversion

Step 1. Run VMware vCenter Converter as an administrator on the management machine where it is installed.

Step 2. From the top menu, click “Convert machine” to launch the conversion wizard.

Step 3. When the wizard is open. Choose “Powered on” and select “Remote Windows machine”. Then enter the IP address or name, user name, and Password.

A powered-on machine is for running a physical machine. And the source does not need to be shut down.

Source System VMware vCenter Converter

Step 4. You will be told that an agent will be installed and be asked to automatically or manually uninstall the vCenter Converter agent after the import succeeds. And select the “Yes” button.

agent uninstall prompt VMware converter

After the agent installation complete, you will see the source machine details.

Step 5. In this window, select destination type, choose “VMware Infrastructure virtual machine.” If your VM is managed by vCenter, enter the server IP, user name, and password. Enter “Next”.

Note: If you want to convert VMware ESXi VMs to VMware Workstation, just choose “VMware Workstation or other VMware virtual machine”.

Step 6. Then select a data center and VM name to store the destination VMware VMs. And click “Next”.

Step 8. In this “Options” step, you can set up the parameters for the conversion task:

  • Data to copy: You can choose the disk or partition that needs to be copied to the destination.
  • Device: Specify the virtual processors, memory size, cores, and more.
  • Networks: Choose a network adapter for your VMs.
  • Service: This allows you to stop running the service on the source Windows before the P2V conversion starts and decide the start mode for the target VMs.
  • Advanced: Configure the “Post-conversion power state” and “Post-conversion processing”.
  • Throttling: Control CPU usage and network bandwidth.

Step 9. Now you will see the conversion details in this Summary step. Click “Finish” if everything is fine.

Now the P2V conversion will start and wait for the process to get finished. Then power on the destination VM you will see a VM named with “converted”.

V2V Migration 

Performing V2V conversion much similar with P2V conversion, but there are subtle differences.

Step 1. Just run VMware vCenter Converter as an administrator. And click “Convert Machine” from the top menu to run the conversion wizard.

Step 2. In the source system, choose “Powered off” as the source type. And choose “VMware Workstation or other VMware virtual machine”. Browse and select a source VM or image. Click “Next”.

Source-system V2V

Step 3. Choose “VMware Infrastructure virtual machine” as the destination type. Enter server, username and password. And click “Next”.

Step 4. Then, just like P2V conversion, set up the Destination Virtual Machine, Destination Location, and Options

Step5. Check all the settings in the Summary. And click “Finish” to submit the task.

Common Errors and Troubleshooting when using VMware vCenter Converter

Error 1: Conversion fails at 1%–2%

Cause: Insufficient free space on the target datastore, or Helper VM network issues.
Solution: Check the available space on the target datastore. For Linux P2V, verify Helper VM network configuration.

Error 2: Linux P2V fails at 1% — “Unable to obtain the IP address of the helper Virtual Machine”

Cause: The Helper VM automatically receives an IPv6 address while the environment is not configured for IPv6, or it cannot obtain an IPv4 address automatically.
Solution:

  • Disable the IPv6 option by unchecking the box under Helper VM network configuration.
  • Manually assign a static IPv4 address to the Helper VM.
  • Ensure the IP address you specify is not already in use on the network.

Error 3: Port connectivity issues — “Unable to contact the specified host”

Cause: Required ports are blocked by firewalls.
Solution: Validate if the required ports are open for VMware vCenter Converter. Reference Broadcom KB articles for the specific port requirements.

Error 4: VM blue‑screens on boot — “STOP 0x0000007B INACCESSIBLE_BOOT_DEVICE”

Cause: Mismatched disk controller driver.
Solution:

  • Verify that the conversion task reached 100% completion.
  • Check whether the VM’s virtual disk controller type (IDE vs SCSI vs NVMe) matches that of the source.
  • Try booting into Safe Mode and installing the correct storage driver.

Error 5: VM fails to boot after conversion — UEFI/BIOS mismatch

Cause: Source machine uses UEFI, but the target VM is configured with BIOS firmware. Note that Converter does not copy UEFI variables to the destination.
Solution: Edit the VM settings and change the firmware from BIOS to EFI. Only the current UEFI boot entry is copied.

Error 6: Converter service status is abnormal

Cause: The Converter Standalone Agent/Server/Worker services are in a starting or stopped state.
Solution: Check and ensure the following services are in “Running” state:

  • VMware vCenter Converter Standalone Agent
  • VMware vCenter Converter Standalone Server
  • VMware vCenter Converter Standalone Worker

Error 7: Network-mapped drive conversion fails

Cause: Previously, selecting a network-mapped drive with a drive letter as the destination VM location would cause conversion failures.
Solution: Version 9.0 now requires UNC paths instead of network-mapped drives for network share destinations.

VMware vCenter Converter Alternative for Large-scale Enterprise Migration

VMware vCenter Converter remains a useful tool for basic P2V and V2V migrations. However, it was designed primarily as a machine conversion utility rather than a complete enterprise migration platform.

Organizations planning large-scale data center modernization projects often encounter challenges that go beyond simple machine conversion, including:

– Cross-platform migrations
– Bulk migration of hundreds of servers
– Automated migration workflows
– Application dependency management
– Migration scheduling and orchestration
– Centralized project visibility and reporting
– Minimal-downtime migration requirements

In these scenarios, a dedicated migration platform such as i2Migration may be a better fit.
