Upgrading from Drupal 7

Migrating a website software version is one of the highest risk task a webmaster has to deal with when managing a website. Drupal 7 Migration? 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.)

When you are done with setting up a local Drupal 8 website, navigate to the Extend tab of the new website and verify that the three main migrate modules (Migrate, Migrate Drupal and Migrate Upgrade) are present in the Core (experimental) section. Though not yet perfect, the upgrade procedure in Drupal has come quite a long way. As you can see in this tutorial, the upgrade process is now very streamlined and is an integral part of the Drupal Core.

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. Depending on which of these two tasks you’re performing you’ll use the tools in different ways.

Download the latest release of the distribution. Download and extract the latest release and copy your existing site’s Drupal 7 version settings.php file and files directory to the sites/default directory in the distribution install. This will point the new site to your existing site database.

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. Most distributions are built using the Features module, which allows exporting configuration from a Drupal site – content types, fields, views, and so on – into code, so that it can be enabled on multiple sites. For components like content types and fields to be exportable, they need to have a “machine name”–a unique name that will be the same on every site they’re enabled on. For example, a date-type field used to store the date of an event might have the machine name field_date. See extra details on Migrating to Drupal 8.
