How can I disable the core migrations?

Question

After I enabled the Drupal Migrate module in Drupal 10, every time I do a drush ms I get a page of errors about Drupal 7 migrations like the following one.

[error] Could not retrieve source count from d6_filter_format: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'PRODUCTION_content_shared.filter_formats' doesn't exist: SELECT COUNT(*) AS "expression"

Is there a way to disable migrations by migration_tags (all the Drupal 6 migrations are tagged "Drupal 6") or if necessary by ID?

Answer 1

Use hook_migrations_plugins_alter.

For example:

/**
 * Implements hook_migration_plugins_alter().
 */
function my_module_migration_plugins_alter(array &$migrations) {
  $migrations = array_filter($migrations, fn(array $m) => $m['provider'] == 'my_module');
}
