# Upgrading

Because there are many breaking changes an upgrade is not that easy. There are many edge cases this guide does not cover. We accept PRs to improve this guide.

## From v2 to v3

This should be a quick update:

- When creating a new project, the default search location for settings classes will be in the `app_path('Settings')` directory. If you want to keep the old location, then you can set the `auto_discover_settings` option to `app_path()`. For applications which already have published their config, nothing changes.
- If you're implementing custom repositories, then update them according to the interface. The method `updatePropertyPayload` is renamed to `updatePropertiesPayload` and should now update multiple properties at once.
- Add a new migration with the following content

```php
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::table('settings', function (Blueprint $table): void {
            $table->boolean('locked')->default(false)->change();

            $table->unique(['group', 'name']);

            $table->dropIndex(['group']);
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::table('settings', function (Blueprint $table): void {
            $table->boolean('locked')->default(null)->change();

            $table->dropUnique(['group', 'name']);

            $table->index('group');
        });
    }
};
```
