Drupal 9 will have all the features of Drupal 8 plus some significant improvements. Drupal migration to the latest version is not automatic. You must install and upgrade from Drupal 8 to 9. In this blog post, we’ll offer step-by-step tips for upgrading your web CMS solution without any hassle. Keep scrolling to get all the tips.

Installing the Drupal 9 Initial Release 

Many software experts would suggest you against installing the initial versions of major software releases. This is because many early versions don’t have all the features that will eventually be introduced. However, that’s not the fact in case of the forthcoming version of Drupal.

Since there’s no feature that you would miss by upgrading early, you shouldn’t wait after the initial release. Drupal 9.0 core code completely matches with the recent version, Drupal 8.9. The only major changes in terms of codes are the removal of deprecated code and third-party dependencies. Some other notable changes in the Drupal 9 include:

  • The requirement of more advanced versions of the PHP framework (PHP 7.3 and above) and databases.
  • Updated versions of libraries (for Symfony and Twig).
  • New libraries for jQuery and UI components of the CMS.

Useful tips for upgrading to Drupal 9

Before upgrading to the newest version of Drupal, make sure that your contributed modules are compatible. The upgrade path for Drupal 9, unlike its previous versions, is comparatively easier. So, if you work on Drupal website development, you can adapt to the new version quickly. Here’s a list of some other important tips for installing Drupal 9.

1. Update the Drupal Core

We have mentioned earlier in this blog that Drupal 9’s core code is similar to Drupal 8.9 except deprecated parts and third-party dependencies. If your website doesn’t have deprecated codes, the upgrade process will be easier. Since you don’t have to remove any code from the core, the upgrade wouldn’t take much effort.

2. Updated Modules

Keep your website modules updates to make sure that you don’t lose them after installing Drupal 9. Except for updated dependencies, Drupal 9 doesn’t have any major new features. If you are considering Drupal migration, starting with Drupal 9 would be great. But keeping your modules updated saves you from the risk of losing them. The new version will support various security fixes after the support for Drupal 8 ends. Drupal 9 upgrade for contributed modules will depend on module maintainers.

3. Custom Codes for Deprecation

If you own a customized Drupal platform, use the deprecation checking and correction tools to locally fix issues. Tools like Drupal Check and Rector are available for checking deprecated codes. Additionally, you can also use an integrated development environment to manage the deprecations.

What’s the deprecated code we’re talking about?

We have repeatedly mentioned the phrase “deprecated code” throughout this blog. We had to since it’s an important part of the Drupal 9 upgrade. Deprecated code is the functions or features of a software that are being replaced with better versions. Deprecated is still part of the software. It’s just that the deprecated part may be removed in the future to incorporate a newer and/or better version.

It is important to note that deprecated is just the status of the code created by developers. It indicates that a better version should be used instead of that code.

Conclusion: Gearing Up for Drupal 9

Besides removing the deprecated code of Drupal 8.9, you need to plan your installation and upgrade process. This includes, among other things, pre-installation auditing and code refactoring. Then you need to address third-party dependencies that require newer versions. If you use contributor modules or customized codes, you need additional efforts. Drupal 9 requires a new version for dependency. It’s better and wiser to plan everything beforehand so you can complete the upgrade process swiftly.
