Drupal Update Process

Only updating security updates.

1. Run drush pm:security to get a list of security updates.
   1. You may need to composer require drush/drush if it's not install already.
2. For each module in the list run composer update drupal/module_name.
   1. For core updates use run composer update drupal/module_name --with-dependencies.
   2. This will update according to the semantic versioning.
3. If you need to update beyond the limitations of the semantic versioning:
   1. Either manually modify composer.json or try something like composer require drupal/core:"~8.8.1". I was not able to get the require method to work.
4. Run drush updb.
5. Run drush cr.
6. Check site. If everything is good run composer update --lock and commit the composer files.
7. On other environments, after running svnu, you can install updates by running composer install.
