updating old drupal 8 via composer

Updating such old Drupal can be stressing. (one passed, but its not rule - try on sandbox/on your own risk)

At first - update drush to version 9.5.x - composer update drush/drush --with-dependencies --dry-run

Run drush updb && drush cr && drush cron

composer outdated drupal/*

composer update drupal/core webflo/drupal-core-require-dev --with-dependencies --dry-run

composer update drupal/core webflo/drupal-core-require-dev --with-dependencies

Run drush updb && drush cr && drush cron
