# Upgrading from 2.x

> This hasn't been tested yet and might not be 100% right. It *should* work well, but note the todo at the bottom of the script for updating the `domains` table.

- Move all `_tenancy_` prefixed keys in tenant storage to `tenancy_` prefixed keys

    Run this **with 2.x code** (but put application down first, this will break your app and require that you update to 3.x immediately after). Of course make a backup of the DB first.

    (Note: You may want to make this part of a migration)

    ```php
    use Stancl\Tenancy\Tenant;
    tenancy()
        ->all()
        ->each(function (Tenant $tenant) {
            $keys = array_keys($tenant->data);
            $keys = array_filter($keys, function ($key) {
                return Str::startsWith($key, '_tenancy_');
            });

            foreach ($keys as $key) {
                $value = $tenant->data[$key];
                unset($tenant->data[$key]);
                $tenant->data[str_replace('_tenancy_', 'tenancy_', $key)] = $value;
            }

            $tenant->save();
        });

    ```

- Add an `id` autoincrement column to `domains` table and retroactively generate the ids

    (Note: You may want to make this part of a migration)

    ```php
    use Illuminate\Support\Facades\Schema;
    use Illuminate\Support\Facades\DB;
    use Illuminate\Database\Schema\Blueprint;

    $domains = DB::table('domains')->get();

    Schema::table('domains', function (Blueprint $table) {
        $table->unsignedBigInteger('id')->nullable();
    });

    $counter = 1;
    foreach ($domains as $domain) {
        DB::table('domains')
            ->where('domain', $domain->domain)
            ->update(['id' => $counter]);
        $counter += 1;
    }

    Schema::table('domains', function (Blueprint $table) {
        $table->dropPrimary();
    });
    Schema::table('domains', function (Blueprint $table) {
        $table->primary('id'); // todo: here we want to make it autoincrement, not just primary
    });
    ```

- Replace your Http Kernel with a stock version (copy it from laravel/laravel: [https://github.com/laravel/laravel/blob/master/app/Http/Kernel.php](https://github.com/laravel/laravel/blob/master/app/Http/Kernel.php)) and add back in any changes you made. The package now doesn't necessitate any Kernel changes, so remove all of the 2.x ones.
- Delete config, publish it & the new files using `php artisan tenancy:install`
- Create Tenant model, as instructed on the [Tenants]({{ $page->link('tenants') }}) page
- Update routes to use the correct middleware, see the [Routes]({{ $page->link('routes') }}) page
