Upgrading to Drupal 8

Updating a website script version is one of the most complicated procedure a webmaster encounters when managing a website. Migrating from Drupal 7 to Drupal 8? Here is a small guide with various details. Let’s start with general info : How to see the NID of a node. If the node is in ‘edit’ mode, you can see the nid in the URL. (A node, in case you’re wondering, is a page like an article or a forum posting. You can design what fields it has and how they is displayed. Typically a node will consist of a heading, some body text, maybe an image, etc. Drupal assigns two URL addresses to each node, a human-friendly one made of words, and a nid, or node id.)

The Drupal core migration system is used for both importing data from custom sources, and for migrating content and configuration from previous versions of Drupal into Drupal 8 — effectively updating your site from one major version to another.

Here are basic steps to take to upgrade an existing Drupal site to use a distribution. These are rough guidelines only. Because each site and each distribution is configured differently, you’re likely to run into additional complexities. But these notes should at least get you started in the right direction. Select a distribution to use. You’ll want to find the distribution that most closely matches your site requirements. See the listings and comparisons of Drupal distributions on drupal.org.

The steps above outline how to get a distribution minimally installed on an existing site. But you’ll still have a lot of work to do to reconcile your existing site content and structure with what has been created by the distribution. Here are a few tips to get you started–but you should begin with the assumption that there will be lots more you’ll discover and need to fix. If the distribution is installed from scratch, we can be sure that the components we’re creating won’t conflict with existing components on the site. But when we’re converting an existing site into a one based on a distribution, there’s the potential that a component we’re creating will have the same name as one that already exists on the site. In certain cases, such a conflict can cause a site error that’s difficult to resolve. See more details about Upgrading from Drupal 7 to Drupal 8.
