D6-D8 migration: Migration of Drupal 6 Images (ImageField module) to Drupal 8 Images works out of the Box!

We are having a Drupal 6 site, which is using ImageField module, for adding images in content type. The content and images migration to Drupal 8 site works out of the box!!

We carried out following steps to see it in action:

1) In D6 site, we added Image field, as provided by ImageField module, in Page content type. We configured this field to have Alt/Title information along with Unlimited number of values.

After adding the field, we created a Page content and uploaded multiple images in Image field along with Alt/Title info. D6 site with Page content looks like below,


2) Next we installed D8 site with default settings. Afterwards we enabled Drupal Upgrade and Migrate Tools contrib modules to do the migration,
drush en migrate_upgrade migrate_tools -y
3) Then we executed the migration using Drush. Either we can run the full migration like below,
drush migrate-import --all
OR we can execute specific migrations for content and images like below,
drush migrate-import d6_field
drush migrate-import d6_field_instance
drush migrate-import d6_field_instance_widget_settings
drush migrate-import d6_field_formatter_settings
drush migrate-import d6_file

drush migrate-import d6_filter_format
drush migrate-import d6_node_type
drush migrate-import d6_user_role
drush migrate-import d6_user
drush migrate-import d6_node__page

In both the cases, content and images of our Page content type gets migrated to D8 site and looks like below,


Note: After the migration, D8 Page content type didn't show Alt/Title information by default. We enabled both the Alt/Title fields under Image field in Page content type. The Alt/Title data was already gets migrated so we just enabled Alt/Title fields to display it.

Secondly image thumbnails were not visible in the Edit screen above so we gave permissions to 'files' folder and cleared the cache. And it worked fine.


It's great that Images uploaded using ImageField module in D6 site gets migrated automatically in D8 site!!

Simple Meditation

Set small goals, such as meditating for two minutes every morning. When that feels OK, up the time to 5, 10 or 20 minutes. 1) Find a comfortable seat - where you can sit up tall, either crosslegged on the floor or in a chair. Close your eyes or soften the gaze so you are not focusing on anything in particular. Place the hands with the palms down on the tops of the thighs. 2) Take a moment to notice the sensation of sitting - become aware of the ground or chair beneath you, and the parts of your body in contact with them. Now bring your focus to your hands, noticing the weight of them on the thighs, and the feel of the fabric of your clothes.  3) Now begin to notice how your breath feels in your body as you inhale and exhale. Make no effort to change the breath, simply let your natural breath flow in and out. 4) Aim to stay focussed on these sensations of the breath, but when you notice the mind wandering, acknowledge the thought, then come back to the breath again.  5) When yo...

Custom MySQL Database to Drupal 8 Migration

Image
There are thousands of websites which are using MySQL as database. If we need to migrate data from Websites, which are using MySQL database, to Drupal 8 then we can use this blog post as starting point. We have a sample MySQL Database 'mysql_custom_db' which contains two tables, users and pages. The data in 'users' table looks like below,   The data in 'pages' table looks like below, As all the fields in 'users' table, from source database, will map to User entity in Drupal 8 site so we don't need make any changes there. But as we are migrating 'pages' table data to 'Basic Page' content type in Drupal 8 site, so we need to create required fields in 'Basic Page' content type. We have created the fields in 'Basic Page' content type and it looks like below, In our migration, field mapping between source site (pages) and destination site (Basic Page' content type) is like below, city...
