Migration
Migration is a term representing moving a WordPress website from one location (e.g. http://localhost/site) to another (e.g. http://site.com).

This is achieved by:

Making a full backup copy of the site
Moving it in the uploads/backup/ directory on the new site
After opening the Backup page a new archive will be displayed in the Backup Archive list.
