Migration-Related Contributed Modules for Drupal 8, 9, 10, and 11

There's a whole ecosystem of contributed modules that build on the Migrate API in Drupal core. They do things like provide Drush commands for working with migrations, add new sources (CSV, JSON, etc.), add new destinations, provide code examples, and fill in other gaps. Think of these as the tools of the trade you’ll use to do your work. In most cases you’ll use these to do the migration, but then once the migration is complete you can remove them from your project.

Then there are the contributed modules that add features to your site. Like Flag, Paragraphs, or Webform. These modules often contain migration-related code that is intended to help make it easier to handle data specific to these modules. There is code in the Flag module, for example, that can help with knowing how to extract flagging records from Drupal 7, and for transforming that data into the format the module expects it to be in for Drupal 10. You might end up having to tweak it a bit, but at least you’re not starting from scratch.

In this tutorial we'll:

  • Look at some of the most commonly used toolset modules.
  • Explain what you can expect to find in standard contributed modules related to migrations.

By the end of this tutorial you should have a better sense of the various tools available to you for authoring a migration.
