composer update acquia/blt -W

Manual Process:

• 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.
+  *
+  * @link https://docs.acquia.com/
+  */

• 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;

Automated Process:

• Use migrate command provided in BLT.
