Create new drupal from old drupal using composer

(For updating 8.9.x in kpci7, cf. https://kpchiaoo.blogspot.com/2018/09/update-drupal.html

 

When using:

composer update --dry-run "drupal/*"

This should show any available minor or patch update, however, my site didn't show any minor version for drupal.

So I follow this: https://www.drupal.org/docs/8/install/add-composer-to-an-existing-site
to create a new site and to transfer my old files to the new site.

1. Create a new drupal site, drupal_new:
cd /home/chiao/public_html
composer create-project drupal/recommended-project:~8.8.0 drupal_new --stability dev --no-interaction

2. Copy files to drupal_new:

    Custom themes go to /var/www/sites/new_html/web/themes/custom/

    Custom modules go to /var/www/sites/new_html/web/modules/custom/

    Libraries go to /var/www/sites/new_html/web/libraries/

    Your uploaded files and images go to /var/www/sites/new_html/web/sites/default/files/
3. Copy sites files:
cd /home/chiao/public_html/drupal_new/web/sites/default
sudo cp -av ~/public_html/drupal/sites/default/settings.php .
sudo cp -av ~/public_html/drupal/sites/default/settings.local.php .
sudo cp -av ~/public_html/drupal/sites/default/files/config_5cKxplPBXz7CfVTT9KjhZ3fJkIg1ygQ2hTdYEM64PUZQUPSy94TTCTcHuJ16-cOW_918dZ1kpw/ files/

cd /home/chiao/public_html/drupal_new/web/sites/
sudo cp -av ~/public_html/drupal/sites/development.services.yml .

change owner, www-data:
sudo chown -R www-data.www-data files/ settings.*

4. Edit composer.json in your new project root (e.g., /var/www/sites/new_html) and copy the list of packages from your old composer.json's "require" and "require-dev" sections to the new composer.jsonfile.

5. rm  ~/public_html/drupal_new/composer.lock
composer install

6. All done for creating new druapl.

7. cd  ~/public_html/drupal_new/
drush state:set system.maintenance_mode 1
drush cache-clear drush
composer update drupal/core-recommended --with-dependencies
drush updatedb
drush cache-clear drush
drush state:set system.maintenance_mode 0
drush cache:rebuild

drupal, All links redirect to Homepage
