Reproduction steps

./yii gii/api
./yii migrate

#again
./yii gii/api

Expected
No more migration

Result

<?php

/**
 * Table for Subscription
 */
class m240205_140005_change_table_subscriptions extends \yii\db\Migration
{
    public function up()
    {
        $this->alterColumn('{{%subscriptions}}', 'start', $this->timestamp()->null()->defaultValue(null));
        $this->alterColumn('{{%subscriptions}}', 'end', $this->timestamp()->null()->defaultValue(null));
        $this->alterColumn('{{%subscriptions}}', 'createdAt', $this->timestamp()->null()->defaultValue(null));
        $this->alterColumn('{{%subscriptions}}', 'updatedAt', $this->timestamp()->null()->defaultValue(null));
    }

    public function down()
    {
        $this->alterColumn('{{%subscriptions}}', 'updatedAt', $this->timestamp()->null()->defaultValue(null));
        $this->alterColumn('{{%subscriptions}}', 'createdAt', $this->timestamp()->null()->defaultValue(null));
        $this->alterColumn('{{%subscriptions}}', 'end', $this->timestamp()->null()->defaultValue(null));
        $this->alterColumn('{{%subscriptions}}', 'start', $this->timestamp()->null()->defaultValue(null));
    }
}

I am not able to reproduce this issue.

I attempted to create failing test for PgSQL:

// above attempt yields this migration which is correct and expected
<?php

/**
 * Table for Subscription
 */
class m200000_000000_change_table_subscriptions extends \yii\db\Migration
{
    public function safeUp()
    {
        $this->addColumn('{{%subscriptions}}', 'updatedAt2', $this->timestamp()->null()->defaultValue(null));
    }

    public function safeDown()
    {
        $this->dropColumn('{{%subscriptions}}', 'updatedAt2');
    }
}

Please provide following details:

• which database do you use
• can you give create table statement of your existing (applied migration) table (e.g. subscriptions table)
