Upgrading a website script version is one of the most complicated procedure a webmaster has to deal with when managing a website. Drupal 8 Upgrade? Here is a small guide with various details. Let’s start with general info : Which modules to use? There are a lot of modules, lots of them doing similar or related things. You want to try not to have too many modules, because they each slow things down a little bit, and because you’ll have to maintain them (by installing updates as they are issued). http://drupalmodules.com has reviews. To help you assess the health and life expectancy of a module, look, on the module’s project page, to see how many people are using it (at the bottom of the page). Look at the top right to see how recently people have been committing to maintaining it.
The very first thing you should do is to make a local version of the website. This is an essential step because making changes to a live website is very risky and is never a recommended practice. This way, if anything does go awry, your actual website will remain safe and functional. 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.
If you’re importing data from a non-Drupal datastore, start with Set up Migrate Demo Site and Source Data . We’ll walk through the process of connecting the migrate system to an external data source, writing custom migration paths, using custom process plugins to transform data during import, and best practices for executing your custom migrations. We’ll primarily look at using an external MySQL database as our data source, but the techniques learned will apply to any data source. We’ll also discuss how to extract data from CSV, JSON, and XML sources.
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.
If you already have a Drupal website that has a considerable amount of content or a large number of users or has custom functionality you want to keep, though, you might want to try directly upgrading the site to use the distribution. Doing so could save you a lot of time in migrating content. But it will also raise a number of challenges. Upgrading to a distribution is probably something you should try only if you have the skills and time needed to do troubleshooting and some custom data work.
Though it’s been over three years since Drupal 8 launched, many companies using Drupal to power their digital experiences have yet to upgrade Drupal 7 to Drupal 8 due to the complexities involved. Many Drupal agencies and general Drupal users have found out the hard way that making the jump from Drupal 7 to Drupal 8 is actually more like a re-build instead of an upgrade. Meanwhile, Drupal continues to release updates to the Drupal 8 core framework, and Drupal 9 is on the horizon for release in mid-2020. As such, the longer these companies put off the Drupal 8 upgrade, the more difficult that eventual upgrade will be when they’re forced to make it.
