# Important: #107629 - Reference Index check moved to Install Tool {#important-107629-1760369226}

See [forge#107629](https://forge.typo3.org/issues/107629)

## Description {#description}

The **Check and Update Reference Index** functionality has been moved
from the **System > DB Check** module (EXT:lowlevel) to the
**Maintenance** section of the **Install Tool** (EXT:install) in the
top level module now called **System**.

> [!NOTE]
> The top-level backend modules were renamed in TYPO3 v14.
>
> For details, see:
> [Feature: #107628 – Improved backend module naming and structure](https://docs.typo3.org/permalink/changelog:feature-107628-1729026000).

This change makes this essential administrative tool more accessible and
better organized alongside other common maintenance tasks such as database
comparison, cache management, and folder structure checks.

### Why this change? {#why-this-change}

The Reference Index is a critical system component that tracks relationships
between records in TYPO3. Checking and updating is a routine maintenance
task that administrators perform regularly, similar to:

-   Analyzing database structure
-   Clearing caches
-   Checking folder permissions

Previously, this functionality was hidden in the **DB Check** module
of EXT:lowlevel, which made it:

-   **Hard to discover**: Administrators had to know where to look
-   **Inconsistent**: Other maintenance tools were in the Install Tool
-   **Less accessible**: Required an additional system extension

## Impact {#impact}

**For Administrators:**

The Reference Index check and update functionality is now directly available
in the Install Tool under
**Maintenance > Check and Update Reference Index**.

Key benefits:

-   **Better visibility**: Found alongside other maintenance tools
-   **No extra dependencies**: Works out-of-the-box without EXT:lowlevel
-   **Consistent location**: All system maintenance tasks in one place
-   **Faster access**: Direct access via the Install Tool
-   **Same functionality**: Check and update operations work exactly as before

**CLI Access:**

The command-line interface remains unchanged and continues to work as before:

```bash
# Check reference index
vendor/bin/typo3 referenceindex:update --check

# Update reference index
vendor/bin/typo3 referenceindex:update
```

## Migration {#migration}

No migration is required. System Maintainers should use the new location
in the **System > Maintenance** section instead of the
**System > DB Check** module.

The functionality works identically to the previous implementation.
