Best way to automagically migrate tests from JUnit 3 to JUnit 4?

" extends TestCase"

@Override
protected void setUp() throws Exception { }

@Before
protected void setUp() throws Exception { }

@Override
protected void tearDown() throws Exception { }

@After
protected void tearDown() throws Exception { }

// Add @Test

// Remove double @Test's on already @Test annotated files
Replace:
^[ t]+@Testn[ t]+@Test
With:
    @Test

// Remove all empty setUp's
Replace:
^[ *]+((public|protected) +)?void +setUp()[^{]*{s*(super.setUp();)?s*}n([ t]*n)?
With nothing
Regular Expression: on

// Remove old imports, add new imports
Replace:
