Apparently, technology is evolving with time, and it ought to be. Because if it will not evolve, then it will become obsolete. There are many examples available of things that didn\u2019t change with time; they got vanished.<\/p>\n
The same happened with our favorite Drupal. We all liked Drupal 7 and then updated to Drupal 8. It also succeeded in impressing us. After using Drupal 8 for many years, now is the time for Drupal 9 migration<\/a>. It is now mandatory because Drupal 8 has already reached its end-of-life in November 2021.<\/p>\n There might be some users who would\u2019ve upgraded to Drupal 9. But there can be some who are still operating the previous version (Drupal 8). Let\u2019s help them and find out how to upgrade to Drupal 9?<\/p>\n Drupal 9 is not entirely different from Drupal 8.9. Drupal Developers have only eliminated the deprecated APIs and used updated dependencies. Drupal 9 is based on a continuous innovation model; thus, you don\u2019t have to be ready for major changes like you get in previous versions.<\/p>\n Drupal 9 has more features and amazing themes. To know more about Drupal 9, switch to this version now.<\/p>\n You need to know a few prerequisites before you upgrade to Drupal 9.<\/p>\n If this checklist is done, then you can start the upgrading process.<\/p>\n There are a few tools readily available to you to complete the upgrade process. In the Drupal 9 upgrade, deprecation and compatibility are the two main factors to pay attention to and these tools will be your savior in this journey.<\/p>\n They understand the deprecation codes and identify them easily.<\/p>\n With the help of this tool, you run a standalone PHP executable from your command line, and it checks all the deprecated codes with Drupal 9 compatibility.<\/p>\n This module is more or less similar to Drupal check. Upgrade status scans the complete site and alerts you if any deprecated code or incompatible module is there on the site. It also suggests you what updates are required to meet the system requirement.<\/p>\n It helps you in two ways, 1. The way above two tools (Drupal check and Upgrade status) assists you, and 2. It configures the module\u2019s test suite if you don\u2019t find the correct deprecated code path. The complete test helps to get the best results.<\/p>\n It helps find deprecated codes with an automated system. Rector easily finds custom and contributed modules that need to fix.<\/p>\n These are five tools that can help you in finding and fixing the problem of compatibility and deprecation. Out of five, you can choose anyone, which is handy to you.<\/p>\n Perform the following steps from your Drupal site\u2019s core (composer.json):<\/p>\n Also, ensure you change the entry in \u2018composer.json\u2019 file after a successful upgrade if you are doing this process for an upgrade to Drupal 9 from Drupal 8.9. Otherwise, you will not be able to install Drupal updates.<\/p>\n “drupal\/core”: “^9.0.0”,<\/p>\n Don\u2019t forget to follow this Drupal maintenance checklist<\/a> to keep your Drupal website up to date!<\/p>\n If you are still using Drupal 8, then your site is at risk. You are running a site that has no security promises with ample loopholes since the version is not live now. So, to protect your database, and to maintain the performance of your site, you should now upgrade to Drupal 9.<\/p>\n Hopefully, the above-mentioned steps will help you to upgrade to Drupal 9 smoothly.
