+
+When upgrading Label Studio, keep the following in mind:
+
+- **Backup Your Data**: Before starting the upgrade, make sure to back up your existing projects, databases, and any custom configurations. 
+- **Review Release Notes**: Check [the release notes](https://github.com/HumanSignal/label-studio/releases) for the version you're upgrading to. Pay attention to any breaking changes or migration steps that may be required. 
+- **Python Compatibility**: Ensure that your Python version is compatible with the new Label Studio release. Label Studio supports Python 3.9 through 3.13.  Using an incompatible Python version can lead to installation errors.
+- **Check for Dependency Issues**: After upgrading, verify that all dependencies are correctly installed. If you encounter missing package errors, you might need to install those packages manually. Running Label Studio in a clean Python environment or virtual environment can reduce the likelihood of package conflicts.
+- **Test Your Setup**: After upgrading, test your Label Studio instance to ensure everything works as expected. Check key functionalities like task loading, labeling interfaces, data export, and any integrations you use.
+- **Troubleshoot Installation Issues**: If you encounter any issues during the upgrade, see [Troubleshoot installation issues](install_troubleshoot).

+
+## Upgrade using pip
+
+```bash
+ pip install --upgrade label-studio
+```
+
+
+## Upgrade using Docker
+
+1. Stop the existing Label Studio container:
+    ```bash
+    docker ps  # Find the container ID or name
+    docker stop <container_id_or_name>
+    ```
+2. Pull the latest Label Studio Docker image:
+    ```bash
+    docker pull heartexlabs/label-studio:latest
+    ```
+3. Start a new container with the latest image, using the same volume mappings as before:
+    ```bash
+    docker run -it -p 8080:8080 \
+    -v /path/to/yourdata:/label-studio/data \
+    -v /path/to/yourfiles:/label-studio/files \
+    heartexlabs/label-studio:latest
+    ```
+    Replace `/path/to/yourdata` and /`path/to/yourfiles` with the actual paths you used previously.
+4. Run database migrations (if necessary). 
+
+    If you encounter any issues after upgrading, you might need to run database migrations:
+
+    ```bash
+    docker exec -it <container_id_or_name> bash
+    cd /label-studio
+    python manage.py migrate
+    ```
+5. Open Label Studio in your browser at `http://localhost:8080` and check that your projects and data are accessible.
+
+
+## Upgrade after installing from source
+
+If you installed Label Studio [using the source in Github](https://github.com/HumanSignal/label-studio), you can upgrade using the following steps. 
+
+<div class="code-tabs">
+  <div data-name="Using Poetry (recommended)">
+
+  If you're using Poetry ([see these instructions](install#Install-from-source)), upgrade with the following steps:
+  
+  1. Navigate to your Label Studio directory (where you cloned the repository). 
+  2. Fetch the latest changes from the repository:
+  ```bash
+    git pull
+  ```
+  3. If you want to upgrade to a specific version, list available tags and checkout the desired one. For example, to upgrade to version 1.14.0:
+  ```bash
+    git fetch --tags
+    git checkout v1.14.0
+  ```
+  4. Install updated dependencies using Poetry:
+  ```bash
+    poetry install
+  ```
+  5. Run database migrations to apply any updates to the database schema:
+  ```bash
+    poetry run python label_studio/manage.py migrate
+  ```
+  6. Collect static files:
+  ```bash
+    poetry run python label_studio/manage.py collectstatic
+  ```
+  7. Restart Label Studio:
+  ```bash
+    poetry run python label_studio/manage.py runserver
+  ```
