Web Hosting - Site Migrations to New Servers
In order to provide Web Hosting customers with the most up-to-date and secure development platforms, we periodically need to migrate existing customer websites from an old server platform to one with newer operating system and web server versions.
Your test site is moved to the new test environment and a preview 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.
Once you've verified that the preview site is ready to serve as the new production site, we schedule a production DNS change with the Campus Hostmasters, after which the migration is complete.
- Production DNS changes with the Hostmasters are
generally scheduled 24 hours in advance to occur on a business day
at 10AM or 2PM (other times can be accommodated if necessary).
- The time-to-live (TTL) on the DNS records is then lowered to five minutes prior to migration, enabling the changes to propagate quickly. All DNS changes can be reversed in a matter of minutes if there are any unforeseen problems.
