php composer.phar require --prefer-dist slavcodev/yii2-yii-bridge "*"

"slavcodev/yii2-yii-bridge": "*"to the require section of your composer.json.
To use this bridge, edit your entry script (index.php)
// Define project directories.
$rootPath = dirname(dirname(__DIR__));
/**

* @var \Composer\Autoload\ClassLoader $loader Registered composer autoloader.
*/
$loader = require($rootPath . '/vendor/autoload.php');
// Load Yii 1 base class
define('YII1_PATH', $rootPath . '/vendor/yiisoft/yii/framework');
// Load Yii 2 base class
define('YII2_PATH', $rootPath . '/vendor/yiisoft/yii2');

// You need version of file after this commit
// @link https://github.com/yiisoft/yii/commit/e08e47ce3ce503b5eb92f9f9bd14d36ac07e1ae9
// define('YII1_BASE_PATH', $rootPath . '/vendor/slavcodev/yii2-yii-bridge/YiiBase.php');
// Include Yii bridge class file.
require($rootPath . '/vendor/slavcodev/yii2-yii-bridge/Yii.php');
// Create old application, but NOT run it!
$gaffer = Yii::createWebApplication($v1AppConfig);
// Create new application and run. Have fun!
$application = new yii\web\Application($v2AppConfig);
$application->run();Now you can use old models in your Yii2 application, i.e
// Access new application
echo Yii::$app->user->id;
// Access old application
echo Yii::app()->user->id;
// Use Yii2 grid, data provider with Yii1 ActiveRecords
echo yii\grid\GridView::widget([
'dataProvider' => new \yii\data\ArrayDataProvider([
'allModels' => User::model()->with('address.country')->findAll(),
]),
'columns' => [
['attribute' => 'id'],
['attribute' => 'name'],
['attribute' => 'address.country.name'],
]
]);
// Save Yii1 AR in Yii2 controller
public function actionCreate()
{
$user = new User();
if ($data = Yii::app()->request->getPost(CHtml::modelName($user))) {
$model->attributes = $data;
if ($model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
}
}
return $this->render('create', [
'model' => $user,
]);
}
