Upgrading an Extension Module

If you have developed an extension module on a previous version of Tripal that you want to upgrade to Tripal 4, the first step will be to assess what kind of components your module can be broken down into. If you haven’t already, it is recommended to first become familiar with Drupal 10’s object-oriented programming principles. In Drupal 10, your module is composed of any combination of entities, fields, plugins, services, controllers and YAML configuration.

If your module provided an entity in Drupal 7, it will also provide an entity in Drupal 10, but you will have to determine whether it is a Configuration Entity or Content Entity.

Making decisions

Keep in mind that your module can be comprised of multiple components at once, and/or implementations of other plugins/services/entities that have already been defined. This process can be overwhelming, but luckily many developers in the Tripal community have a lot of experience with developing in Drupal 8+ (including Tripal 4 itself, which is comprised of many many many different components!). We recommend first reading through the Extending Tripal section of this documentation. Additionally, please consider joining our weekly Tripal codefests and joining our Slack channel, and someone will be happy to help you with the decision making process.
