title: Migrate Docker Toolbox
---

This page explains how to migrate your Docker Toolbox disk image, or images if
you have them, to Docker for Windows.

In version 18.01.0 and higher, the Docker for Windows installer no longer
prompts users to migrate from Docker Toolbox--you must do so manually.

## How to migrate Docker Toolbox disk images to Docker for Windows

> **Warning**: Migrating disk images from Docker Toolbox _clobbers_ Docker
> images if they exist. The migration process replaces the entire VM with your
> previous Docker Toolbox data.

1.  Install [qemu](https://www.qemu.org/){: target="_blank" class="_"} (a machine emulator): [https://cloudbase.it/downloads/qemu-img-win-x64-2_3_0.zip](https://cloudbase.it/downloads/qemu-img-win-x64-2_3_0.zip).
2.  Install [Docker for Windows](install/){: target="_blank" class="_"}.
3.  Stop Docker for Windows, if running.
4.  Move your current Docker VM disk to a safe location:

    ```shell
    mv 'C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks\MobyLinuxVM.vhdx' C:/<any directory>
    ```

5.  Convert your Toolbox disk image:

    ```shell
    qemu-img.exe convert 'C:\Users\<username>\.docker\machine\machines\default\disk.vmdk' -O vhdx -o subformat=dynamic -p 'C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks\MobyLinuxVM.vhdx'
    ```

6.  Restart Docker for Windows (with your converted disk).

## How to uninstall Docker Toolbox

Whether or not you migrate your Docker Toolbox images, you may decide to
