Acquia has announced the end of life for BLT. For more details, see acquia#4736

* BLT users must upgrade to at least BLT 13.5.x to upgrade to PHP 8.1. and Drush 11.0.7 (or beyond).

PHP 8.2, Drush 12, and Drupal 10 support is unstable.

• Update the BLT plugin to the latest release, which includes acquia/drupal-recommended-settings OOTB.

composer update acquia/blt -W

• Remove BLT reference from settings.php file located at /docroot/sites/<site-name>/settings.php.

- require DRUPAL_ROOT . "/../vendor/acquia/blt/settings/blt.settings.php";
- /**
-  * IMPORTANT.
-  *
-  * Do not include additional settings here. Instead, add them to settings
-  * included by `blt.settings.php`. See BLT's documentation for more detail.
-  *
-  * @link https://docs.acquia.com/blt/
-  */
  require DRUPAL_ROOT . "/../vendor/acquia/drupal-recommended-settings/settings/acquia-recommended.settings.php";
  /**
   * IMPORTANT.
   *
   * Do not include additional settings here. Instead, add them to settings
   * included by `acquia-recommended.settings.php`. See Acquia's documentation for more detail.
   *

   */

• Update default.local.settings.php and local.settings.php to use the Environment Detector provided by this DSR plugin instead of BLT:

- use Acquia\Blt\Robo\Common\EnvironmentDetector;
  use Acquia\Drupal\RecommendedSettings\Helpers\EnvironmentDetector;

• Use migrate command provided in BLT.

./vendor/bin/blt blt:migrate
