# Quickstart: Migration Dashboard Grid

## Overview
The Migration Dashboard Grid allows users to select dashboards for migration using a rich interface with filtering, sorting, and status indicators.

## Usage

1.  **Navigate to Migration Page**: Go to the Migration section in the app.
2.  **Select Source Environment**: Choose the Superset environment you want to migrate from.
3.  **View Dashboards**: The grid will automatically load the list of available dashboards.
    - **Filter**: Type in the "Search dashboards..." box to filter by name.
    - **Sort**: Click on column headers (Name, Last Modified, Status) to sort.
    - **Paginate**: Use the "Next" and "Previous" buttons to navigate through pages.
4.  **Select Dashboards**:
    - Click individual checkboxes to select specific dashboards.
    - Click the "Select All" checkbox in the header to select **all** dashboards matching the current filter (even those on other pages).
5.  **Proceed**: Once selection is complete, click "Next" to configure mappings.

## Troubleshooting

-   **"No dashboards found"**: Ensure the source environment is correctly configured and accessible.
-   **Slow loading**: If the environment has thousands of dashboards, the initial load might take a few seconds.
-   **Status "Unknown"**: If the API fails to return publication status, it will default to a neutral state.
