Drupal 8.5 updating/upgrading workflow

So let’s see if I have figured the Drupal/Composer work flow:

Given that using Update Manager and Composer are not the best idea on a production site.  Also since I’m on a shared server at a Hosting Company (HostGator) I can’t run composer on the same server as the production site.  Because of that I will have a Linux PC with Composer and Drush for development and testing.

On the Development PC:

  • install Drupal and modules with composer/drush to match the current production site.
  • import a copy of the production database
  • test to ensure the development site is working the same as the production site.
  • add Drupal and associated modules (install or upgrade) using composer and drush.
  • test the development environment to ensure upgrades/installs were successful.
  • FTP the files (except for settings.php) to the production environment

On the Production Server:

  • run update.php
  • test production site

What am I missing?

Questions?

  1.   Where is the information kept so that Drupal knows what needs to be updated? 
  2.   If I have added modules or upgraded modules on the development server and enabled them with drush, will the modules be enabled on the production server once they have been ftp’d?
  3.  I assume that since I have not copied the development database back to the production server, new configuration changes (eg new rules for the Rules module) will need to be recreated in the production environment.
