This section contains tips on how to install Drupal from scratch, how to apply routine point release updates, and how to migrate between major version of Drupal. There is also a guide to moving sites from development (either on your local computer, or on a development server) to a production environment (e.g. OIT Web Hosting). For more generic but also more official guidance, the official Drupal website has a Guide to Migrating a Drupal Site.
Please be cautious in using any of the information provided here in conjunction with upgrading or migrating a production Drupal site: always make backups of your live production site first, so that if anything goes wrong, you can revert back to the old version of the site.
