Demo of the Drupal 8 migration system prepared for the Bangkok Drupal Meetup

Demo for "Intro to Migrate in Drupal 8"

This is demo code prepared for the Bangkok Drupal Meetup on March 31, 2016. It demonstrates a basic Drupal 7 to Drupal 8 content migration using the Migrate module and Drush. Content being migrated includes: organisations (nodes), countries (taxonony terms), and people (users). Drush scripts to populate sample content are included.

Drupal 7 Setup

1. drush make https://raw.githubusercontent.com/milesw/migrate_demo/master/d7.make migrate_demo_d7
2. Install Drupal 7 Standard profile
3. drush en -y migrate_demo
4. drush populate-all

Drupal 8 Setup

1. drush make https://raw.githubusercontent.com/milesw/migrate_demo/master/d8.make migrate_demo_d8

2. Install Drupal 8 Standard profile

3. drush en -y migrate_demo

4. drush config-set "system.site" uuid "7322b825-4dc6-437e-9c00-0abfdc04ce8a"

5. Load the d8_config.tar.gz from this repo at /admin/config/development/configuration/full/import (may need to delete shortcut entities from the database?)

6. Add database connection for D7 site to D8 settings.php:

   $databases['migrate']['default'] = array (
     'database' => 'dbname',
     'username' => 'dbuser',
     'password' => 'dbpass',
     'host' => '127.0.0.1',
     'port' => '3306',
     'driver' => 'mysql',
   );
   

7. drush migrate-status (if you see totals, database connection is good)

8. drush migrate-import --all

Editing migrations

When you change the YAML config for a migration you need to reload the config. The recommended way seems to be reinstalling the module, but that can be a hassle.

The config_devel module includes a drush command for reloading config:

drush config-devel-import-one path/to/migrate.migration.users.yml
