When you purchase a package (Gold, Diamond), your website remains intact, meaning all information added remains on the website. You won't loose any data or information. When a new package has been purchased, the features of that package become available for you to use. For example, purchasing a Diamond package comes with an option of purchasing a custom.co.za domain name feature and removes all adverts.  This means that to purchase a custom domain name, you must be on the diamond package.
