In order to provide Web Hosting customers with the most up-to-date and secure hosting platforms, we periodically migrate existing customer websites from an old server platforms to ones with newer operating systems, web server versions and web hosting automation software.
Your test site is moved to the new test environment and a preview / future production location is set up on the new production environment. This allows you to check functionality of the future production site before the DNS migration occurs.
NOTE: For more accurate testing and checking of functionality with your applications (for example Shibboleth, WordPress, etc.) we will instruct you on how to update your local hosts file. This will allow you to point your production domain to the new IP on the new server so that you can interact and test with the site as though it has migrated to the new servers.
Once you've verified that the preview / future production site is ready to serve as the new production site, we'll schedule a production DNS change with the Campus Hostmasters, after which the migration is complete.
