Drupal 7 To Drupal 8 / Drupal 9 Migration? 10 Things You Should Know

Parent Feed: 

Now that you have enough reasons to migrate to Drupal 8 or 9 from Drupal 7. We have listed out ten essential things that you should remember before you begin the Drupal 7 to 8 migration:

Migrate from drupal 7 to drupal 9

1. Observe and Plan

For a smooth Drupal content migration, first Identify the content types and structure of the existing site and note down the observations. Note down the field types, blocks, content types, taxonomies, etc.

Note down what you need to migrate and what you need to merge based on these observations. Check the Views and other site configurations and note them to replicate them in Drupal 8.

2. Create a checklist of Drupal 7 website modules

First, identify modules that you still need, or if the Drupal 7 module has moved to Drupal 8 Core. keep in mind that not every Drupal 7 module is automatically migrated to Drupal 8. Some of the Drupal 7 modules may have put their functionality into a single Drupal 8 module, and some may have separated their features into two or more Drupal 8 modules.

3. Update to the latest available version

Update your Drupal 7 to the latest available version of Drupal 8 or 9. It will ensure cleaner automatic upgrades of Drupal 7 modules with direct Drupal 8 or 9 upgrade paths.

4. Access.

Before migration, make sure you can access the Drupal 7 website's database and files - both public and private.

5. Backup your website

Before you start the Drupal 7 migration process, make sure to create a backup of the Drupal 7 website and use it for the Drupal 8 migration. Although the Drupal migration does not modify the source, It is still not good to migrate a live functional website.

6. Download a fresh installation

Download a fresh installation of Drupal 8 and again, remember, it MUST be FRESH! If you have done configurations or created content, it will be overwritten automatically when a Drupal 8 upgrade is performed.

7. Familiarize yourself

Unlike in previous version upgrades, you cannot perform a direct upgrade from Drupal 7 to Drupal 8. Drupal 8 Migrate module, Drupal 8 Migrate Drupal module and Drupal 8 Migrate Drupal UI module are three modules in Drupal core. You need to familiarize yourself with Drupal 8's migration system and configuration.

8. Decide the choice of migration

Drush (which gives you granular control) browser user interface (more accessible but less control) are two of the choices you have. You can opt for the method that suits your familiarity level and experience.

9. Know your source

The flexibility of the Drupal content migration system allows you to extract content and load from older versions of Drupal and other sources like CSV, XML, JSON, MYSQL, etc.

10. Perform a content audit

Perform a thorough content audit on the Drupal 7 version to identify content you need to migrate to Drupal 8 or 9. For a smooth Drupal content migration, remove the unused and irrelevant content to avoid spending time and effort migrating them.
