Apply for a Web Hosting account today if you are interested in migrating your site!
When transferring an existing website over to the Web Hosting Service, we first create the space for the site on one of our servers under a “preview URL” that allows you to publish and view the site. See Web Hosting - Site Migrations to New Servers.
If the new site setup meets your expectations, we schedule a DNS migration with the Campus Hostmasters (or another DNS authority) so that the production domain for your site resolves to the one on our server. The entire process is seamless from the site users' perspective.
Note: 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.
