How to move WSL distro in Windows 11 to another drive

Introduction:

In the world of development and system administration, Windows Subsystem for Linux (WSL) has become a valuable tool. It allows users to run a Linux distribution alongside their Windows environment, opening up a world of possibilities for developers and administrators. In this article, we’ll guide you through the process of migrating a WSL instance, using a real-world example, step by step.

Prerequisites:

Before we begin, ensure that you have the following prerequisites in place:

Windows 10 or later with WSL installed.
An existing WSL instance (in our case, Ubuntu).
Sufficient storage space for the migration.

Step 1: Create a Target Directory

To start the migration process, we need a target directory to store the migrated WSL instance. In PowerShell, use the ‘mkdir’ command to create this directory. In our example, we create a directory named ‘D:\WSL\Ubuntu’:

mkdir -p D:\WSL\Ubuntu

Step 2: List All Running WSL Instances

Before we proceed further, let’s list all the running WSL instances. The following command will display a list of all WSL instances, including their state and version:

wsl -l --all -v

Step 3: Export the Source WSL Instance

Now, let’s export the source WSL instance (in our case, ‘Ubuntu’) into a tar file. This step automatically shuts down the WSL instance and restarts it after the export:

wsl --export Ubuntu D:\WSL\Ubuntu.tar

Step 4: Unregister the Source WSL Instance

Once the export is complete, we need to unregister the source WSL instance to avoid conflicts. Use the following command:

wsl --unregister Ubuntu

Step 5: Confirm Unregistration

To confirm that the source WSL instance has been successfully unregistered, run the following command:

wsl -l --all -v

Step 6: Import into the Target Directory

Now it’s time to import the previously exported WSL instance into the target directory. In this step, we specify the target directory and version (in our case, version 2):

wsl --import Ubuntu D:\WSL\Ubuntu D:\WSL\Ubuntu.tar --version 2

Step 7: Verify the Migration

To ensure that the migration was successful, list all WSL instances once again:

wsl -l --all -v

Step 8: Access the Migrated WSL Instance

Now, you can access the migrated WSL instance by using the following command:

wsl -d Ubuntu

Conclusion:

Migrating WSL instances is a powerful way to manage and organize your development environments. By following these steps, you can seamlessly move your WSL instances to different directories or machines, ensuring flexibility and efficiency in your development workflow. Keep in mind that WSL provides a bridge between Windows and Linux, allowing you to enjoy the best of both worlds.
