Guidelines on upgrading your Developer Portal from Drupal 9 to Drupal 10
Information about the upgrade of the Developer Portal from Drupal 9 to Drupal 10.
The Developer Portal is based on the open source Drupal content management system. From API Connect 10.0.5.3, Drupal 9 is upgrading to Drupal 10, which also requires PHP 8.1. All existing Developer Portal sites will be upgraded to, and all new sites will be based on Drupal 10. Therefore, all modules and themes on your Developer Portal site must be compatible with Drupal 10 and PHP 8.1. The core modules and themes are automatically made compatible as part of the upgrade. However, if your Developer Portal sites contain any custom modules or themes, either written in-house or contributed by the Drupal community, it is your responsibility to ensure that they are Drupal 10 and PHP 8.1 compatible before the upgrade.
Upgrading from older versions of API Connect v10
If you are upgrading to 10.0.5.3 from 10.0.1.7 or earlier, or coming from 10.0.5.0 or earlier, your Developer Portal sites will first be upgraded to Drupal 9.5 and then to Drupal 10. This is because upgrading to Drupal 10 requires your site to be on at least Drupal 9.4.4.
Note that if you are in the category where a double upgrade occurs, your Developer Portal sites are going to take double the time to upgrade compared to your normal experience, because upgrading from Drupal 9 to Drupal 10 is a major upgrade. Therefore, when you are planning your maintenance window for upgrading to 10.0.5.3, you need to be aware of the extended time frame. To shorten your upgrade window, consider removing the Developer Portal sites that you do not need.
