PHP Requirements for Drupal 9: Drupal 9 dropped support for Symfony 7.0, 7.1, and 7.2 and new installs require PHP 7.3 or later. Web Server Requirements for Drupal 9: Apache 2.4.7 Here are the major upgrades to consider:ĭatabase and Server Requirements for Drupal 9: MariaDB 10.3+ or MySQL/Percona 5.7.8+ Routine upgrades on a server can take anywhere from a few minutes to hours. If PHP is out of date or MySQL is old – these will need to be updated.

Server Settings and Configurations for Drupal 9Īnother reason why a Drupal 9 upgrade could be time consuming is because of server settings and configurations. But it will likely affect the performance of the Drupal 9 site. Technical debt won’t usually show up in an analysis report that is primarily looking at modules and the functionality of a site. For example, if a developer puts content in the theming layer, this slows down your site and causes headaches if a new design is implemented.

If a site has been accumulating technical debt, then that will need to be refactored.Īnd technical debt is basically corners cut that will need to be redone or fixed. It can be that simple.īut just because the upgrade can be easy doesn’t mean that it will be. Some Drupal 8 sites were able to move to Drupal 9 on the day that D9 was released. So, how does an estimate for a Drupal 8 to 9 migration go from one day to two weeks? Technical Debt and Drupal Version Upgrades Once we looked deeper into the site, though, it became clear that this was a two-week migration process. Now, developer estimates are often incorrect, there’s usually unforeseen problems with a site and requirements from product owners that an analysis won’t take into account. Some developers at Agileana were recently looking at a Drupal 8 site, did an analysis, and assumed the move to D9 would take a day of work. Drupal 9.9.x will be similar to Drupal 10.īut do not underestimate the amount of work it’ll take to make the move to D9. In the future, Drupal 8.9.x is going to be nearly identical to Drupal 9.

There’s a number of advantages to this, and some downsides, but let’s focus on the ease of upgrades. Developers within the Drupal community considered the move from D7 to D8 more of a replatforming than a migration.ĭrupal 8 and 9 and 10 and 11 and so on are built on top of a Symfony framework. In previous versions of Drupal like Drupal 7 and under, the migration process was a big effort. It is likely going to be much easier to move from Drupal 8 to 9 than from 7 to 8.
