+Stop the Docker daemon:
+>sudo systemctl stop docker
+Copy existing Docker data: If you already have images, containers, and volumes that you want to keep, you'll need to move them to the new location. Replace /new/path with the path to the directory where you want Docker to store its data.
+
+>sudo rsync -aP /var/lib/docker/ /new/path/docker
+Edit the Docker configuration file: Open the Docker configuration file with a text editor like nano or vi. The location of this file might vary depending on your Linux distribution, but it's typically found at /etc/docker/daemon.json. If the file doesn't exist, create it.
+
+
+>sudo nano /etc/docker/daemon.json
+Then add the following content, again replacing /new/path with your desired path:
+
+
+{
+  "data-root": "/new/path/docker"
+}
+Save and close the file.
+
+Start Docker again:
+>sudo systemctl start docker
+Verify the changes: Run a command like docker info | grep "Docker Root Dir" to ensure that Docker is using the new directory.
+
+Optional - Clean up old data: If everything is working fine, and you have made a backup, you may want to remove the old Docker directory to free up space:
+
+
+>sudo rm -rf /var/lib/docker/
