  • Migrate Drupal comprises the entire classes needed for upgrade or migration from Drupal 7 to 8.

Be Aware of The Potential Problems

When you Upgrade Drupal 7 to Drupal 8, there are typically two problems that you might come across.

  • The major issue is related with missing migration paths, with Views not being migrated automatically yet.

  • The second widely prevailing issue is that the contributed modules may not be migrated properly.

Identification of Contributed Modules

Before moving ahead with Drupal 8 Migration, identify the contributed modules being used on your current website. Once you have a list of these modules, check whether they have a version compatible with Drupal 8. If not, you can expect some glitches related to the move. However, Drupal 8 has evolved and has several key modules already supporting it. The available update path can be checked through the Migrate UI modules.

Start With The Upgrade Process

Now that you are all set, you can start the process for Drupal 7 to 8 Upgrade. Typically, it is a multi-step journey explained as follows:

Get The Latest Version:- The next step would be to access the official site of Drupal and download the latest version of the CMS.

Make a Local Drupal 8 Site:- Once done with the download, create a local Drupal 8 site as well for using as the destination site for migration.

Verify The Migrate Upgrade Modules:- Verify the presence of all the three main migrate modules, namely Migrate, Migrate Drupal and Migrate Upgrade, in the Core section by navigating to the Extend tab of the new site.

Enable The Modules:- After verifying the modules, enable them and click the Install button at the bottom.

Navigate To The Upgrade Path:- Once the modules are installed, navigate to the upgrade path. For this, you need to go to www.yoursite.com/upgrade (yoursite stands for the name of your Drupal 8 site). Here, you will reach a screen, where some instructions have to be followed for proceeding.

Enter The Details:- In the next screen, you need to enter such as the existing site’s credentials, database location, and the location of the site’s files.

Start The Migration:- Next, you will reach Migrate UI. Here, you can check the potential issues you may come across as well as verify the available and missing paths. Once you check everything, get started with the migration.
