How to migrate users from one website to another website? I created a Drupal Kickstart site and when updating I created another test site. During the updating process my older site has new members and orders how do I transfer the new database tables to reflect the new changes (members and orders) from the older site?
Users Export to export the user from your Kickstart and User Import to your new website.

For the future you should use consider using something similar to Deploy or Configuration Management so you can keep track from your changes.
