Your Website Maker site will always be hosted on the MAGIX server, but you could create a link to the other host. To do this you can export the link to the MAGIX site and then embed this into your existing site.

To do this:

1. Click "Menu"
2. "Export website"
3. Copy the HTML text.
4. Paste this into the index page on your other website.
5. Save and upload this page.
6. Finished.

NOTE: This will mean that you are having to pay for two services. Perhaps you could link the site until your domain name contract runs out and then investigate whether it would not be cheaper transferring the domain to MAGIX. Or, at least making sure you have the smallest possible package with the other provider, as all you need there is enough space for a simple link.
