It is hard to believe that almost 6 years passed since Drupal 8.0.0's release on November 19th 2015. What feels like it was just yesterday, Drupal 8 brought lots of amazing new things to the platform. Near and dear to my heart was full multilingual support that I worked on with over 1600 people for several years. Also stars of the Drupal 8 show were content authoring with the bundled CKEditor, the vastly improved configuration management system, Views in core, built-in web service support, more semantic markup, in-place editing, PHPUnit integration, better caching, improved accessibility, even aural announcements for page changes, and so on and on. Drupal 8 embraced collaboration within the PHP ecosystem and beyond with our use of Symfony, Twig, Guzzle and gradually embraced application of Composer.
With one day to go until Drupal 8's end of life (on November 2, 2021), now is a good time to take stock of your Drupal 8 sites' modules. Use Upgrade Status to check for environment and module compatibility with Drupal 9. Given that there is only one day left, you will highly likely not be on Drupal 9 tomorrow.
With two days to go until Drupal 8's end of life (on November 2, 2021), now is a good time to take stock of your Drupal 8 sites' modules. Use Upgrade Status to check for environment and module compatibility with Drupal 9.
Drupal 8 was released on November 19th, 2015. The end of life comes on November 2, 2021, after almost 6 years of support. Is this too soon? I think the answer will be different from situation to situation. But why do we need to end of life Drupal 8 in the first place?
With three days to go until Drupal 8's end of life (on November 2, 2021), now is a good time to take stock of your Drupal 8 sites' modules. Use Upgrade Status to check for environment and module compatibility with Drupal 9.
Unless you are on Drupal 8.8.x or Drupal 8.9.x, Upgrade Status will tell you to move to that version first, before you can upgrade to Drupal 9. (At this point it should really tell you that 8.9.x is the only acceptable version to upgrade to). Why is that?
With four days to go until Drupal 8's end of life (on November 2, 2021), now is a good time to take stock of your Drupal 8 sites' modules. Use Upgrade Status to check for environment and module compatibility with Drupal 9.
With five days to go until Drupal 8's end of life (on November 2, 2021), now is a good time to take stock of your Drupal 8 sites' modules. Use Upgrade Status to check for environment and module compatibility with Drupal 9.
With six days to go until Drupal 8's end of life (on November 2, 2021), now is a good time to take stock of your Drupal 8 sites' modules. Use Upgrade Status to check for environment and module compatibility with Drupal 9.
While a lot of Drupal extensions are now compatible with Drupal 9, it can happen that you encounter an incompatible extension. In case adopting the extension fits into your plans, that is the best way forward. However, there may be some delay until you can adopt the project and it may not fit into your plans to adopt in the first place. There are a few solutions to use drupal.org projects that are distributed as incompatible on your Drupal 9 sites.
With seven days to go until Drupal 8's end of life (on November 2, 2021), now is a good time to take stock of your Drupal 8 sites' modules. Use Upgrade Status to check for environment and module compatibility with Drupal 9.
Various people in the Upgrade Status issue queue are concerned about the module requiring Composer though. While Drupal 8 or 9 do not require Composer to work, getting any extension installed on your site that depends on third party components is a sizeable challenge without Composer. With Drupal 8 core dependent on various third party components, it was inevitable that a dependency manager will be needed to build Drupal sites. Upgrade Status itself does require various third party components to check for deprecated API uses and even to locate your Drupal site root. So you cannot avoid using Composer to even check for Drupal 9 compatibility.
With eight days to go until Drupal 8's end of life (on November 2, 2021), now is a good time to take stock of your Drupal 8 sites' modules. Use Upgrade Status to check for environment and module compatibility with Drupal 9. While more than 7 thousand modules are now Drupal 9 compatible, there are still various that are not yet compatible. However, most only need a one line change and a release or even if they need more, an automated fix is posted to their issue queue and is tested by the community.
With the Drupal 8 end of life in a little over two months and Drupal 10's release next year, this is the time of transitions again at Drupal. However, while Drupal 7 to 8 (or 9) was a big move, the transitions from 8 to 9 and 9 to 10 are much smaller and mostly automated.
Drupal 10 is planned to be released in June, August or December 2022 and the tools are getting ready to support that. The two key tools will be the same as the previous upgrade: Upgrade Status and Drupal Rector.
Matt Glaman has been doing amazing work recently in the underlying components of both tools. Thanks to his work on updating phpstan-drupal for Drupal 10 support, Upgrade Status checks deprecated API uses on Drupal 9 too. Since my last update on that, I added reporting of deprecated modules and new system requirements as well.
