Assuming that you are using "Docker Desktop WSL 2 backend"

Duplicate of #5829

Solution by @thijsputman #5829 (comment)

Using Powershell/cmd

wsl --shutdown
wsl --export docker-desktop-data docker-desktop-data.tar
wsl --unregister docker-desktop-data
wsl --import docker-desktop-data X:\path\to X:\path\to\docker-desktop-data.tar --version 2

Where "X:" is the disk you want to move .vhdx to.

Microsoft reference for wsl --import args:
--import <Distro> <InstallLocation> <FileName>

As @thijsputman said:

It's sufficient to move the docker-desktop-data WSL-distro. The other one (docker-dekstop) gets restored to its original location when you update Docker Desktop – it's small and doesn't grow in size when using Docker.

Thanks for the correction

Thanks, @efelippe, closing as dupe.

the example is missing the target dir, for me this worked:
wsl --import docker-desktop-data D:\docker D:\docker\docker-desktop-data.tar --version 2

My bad, thanks for correction. Edited my answer. 👍
