How do I migrate the basic page content to another site? I have nearly 250  basic pages content and I want to migrate the same content to another Drupal website. I tried using the Backup and Migrate  module, but it doesn't work well. How can I do this?
As far as I understand from your short question, you want to export only some content to another Drupal installation. In this case Backup and Migrate module will not do any good for you, because it is mainly designed for backing up migrating at database level.

Node Export will allow you to export and import nodes to another Drupal installation. 


  Using this module you can save yourself a lot of time setting up new
  websites that have similar nodes to websites you've already made,
  migrating nodes to new Drupal versions, or between
  development/staging/production sites.
