Migrating a website script version is one of the most complicated procedure a webmaster has to deal with when managing a website. Drupal 8 Migration? Here is a small guide with various details. Let’s start with general info : Be careful where you put your optional modules and themes. Within the folders of your Drupal installation, there is a folder called ‘modules’ and one called ‘themes.’ These are NOT where you should put any contributed modules and themes that you add to your core installation. These folders are just for the core modules and themes. The folders you should use are a second set also called modules and themes, which sit within the ‘sites’ folder in your Drupal installation.

Drupal 8 turned one in the November of 2016. It is about time that the Drupal 7 website owners and administrators should start considering upgrading the websites to Drupal 8. With the Drupal team focused on improving Drupal 8, it is inevitable that Drupal 7 will stop getting official updates in the near future. The great thing about upgrading to Drupal 8 is the remarkably easy process as a result of the inclusion of a few great migration modules in its core. When done with the installation of the modules, you will have to navigate to the upgrade path. For this, go to www.yoursite.com/upgrade (remember to replace yoursite with the name of your Drupal 8 website). You will be brought to the following screen. Please make sure you follow the directions on the screen before proceeding.

Upgrading is the process of moving your site from a previous major version of Drupal to a newer version, for example from Drupal 7 to Drupal 8. This consists of upgrading the codebase to the appropriate version and then migrating the data from your old site into the new one. Drupal 8 core contains two modules to help facilitate this process: Migrate Drupal and Migrate Drupal UI.

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.

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.

You must first understand how your current site is built, and this starts with taking an accurate inventory of the Drupal modules you are currently using. This information is pretty easy to find (Administer > Site building > Modules, or go to the Available Updates page at admin/reports/updates), and this type of preparation will come in handy a bit later in your upgrade process. Will I still need this particular module in Drupal 8? Your Drupal developers are best positioned to answer this question, and they’ll certainly need some knowledge of Drupal 8 core modules ahead of time before giving a definitive “yes” or “no.” Read extra info at https://www.95visual.com/blog/migrating-from-drupal-7-to-drupal-8-and-beyond.
