Upgrading from Drupal 10
While you're still on Drupal 10, update bootstrap to 5.0.2 with composer require drupal/bootstrap:^5.0. Then run drush updb. That release works on both 10 and 11, so it won't block the core upgrade.
Drupal 10 security support ends on December 9, 2026. To see every module on your site at once, scan your composer.lock. The scan is free, runs in your browser, and gives you a fixed price for the whole upgrade.
