Django 1.7 の Django アプリ間でモデルを移行するにはどうすればよいですか?

<code class="python">python manage.py makemigrations old_app --empty</code>

<code class="python">class Migration(migrations.Migration):

    dependencies = []

    database_operations = [
        migrations.RenameModel('TheModel', 'newapp_themodel')
    ]

    state_operations = [
        migrations.DeleteModel('TheModel')
    ]

    operations = [
        migrations.SeparateDatabaseAndState(
            database_operations=database_operations,
            state_operations=state_operations)
    ]</code>

<code class="python">python manage.py makemigrations new_app</code>

<code class="python">class Migration(migrations.Migration):

    dependencies = [
        ('old_app', 'above_migration')
    ]

    state_operations = [
        migrations.CreateModel(
            name='TheModel',
            fields=[
                ('id', models.AutoField(verbose_name='ID', serialize=False, auto_created=True, primary_key=True)),
            ],
            options={
                'db_table': 'newapp_themodel',
            },
            bases=(models.Model,),
        )
    ]

    operations = [
