Microsoft has already started the migration by providing the users option to migrate their existing spaces. Though there is no dead line set for the migration, it is believed that Microsoft may shut down the support very soon as Windows Live users who wanted to create new blogs are already redirected to Word Press
It is expected at least 15 million, nearly half of the 30 million live space users to migrate to “WordPress.com”. WordPess already has nearly 14 million blogs hosted.
