Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.Problem/Motivation
- Drush 10 required for Drupal 8.4+ / Drupal 9: https://www.drush.org/latest/install/#drupal-compatibility
- Migrate Tools 5x required for Drush 10: https://www.drupal.org/project/migrate_tools
- GatherContent requires Migrate Tools 4x: https://git.drupalcode.org/project/gathercontent/-/blob/8.x-5.x/composer...
Steps to reproduce
- Try to run `composer require drush/drush drupal/migrate_tools drupal/gathercontent` on a Drupal 9 site
Proposed resolution
- Update composer.json to require migrate_tools 5x. I've done this manually and am able to run migrations as normal.

hugronaphor commentedAlso, `"drupal/core": "^8.7"` line prevents me installing it

mmjvb commentedSuggest the proper constrain already used for migrate_plus: ^4 || ^5.
Obviously, pinning on one dev branch is very bad, should have been ^4. See no reason to force ^5 and removig support for ^4.
Comment #6
emek commentedThe wrong dependency for Drupal core stops us from upgrading to Drupal 9, so we need this code to get added.
Changed the dependency for migrate_tools to the suggestion in #5.
