Add migrate support for D6 fieldgroup

Related:
For anybody using CCK version 3.x and the 'content_multigroup' submodule (which offers a "multiple fieldgroup") and looking for a migration path:

The corresponding functionality in Drupal 8 will be the field_collection module.
#2612722: D6 -> D8 migrate cck "content_multigroup" to field_collections

Module works! I tested the patch in combination with the migrate upgrade UI module which works as long as you add a path in MigrateUpgradeForm.php:

...
    'd6_field_group_entity_form_display' => [
      'source_module' => 'fieldgroup',
      'destination_module' => 'field_group',
    ],
    'd6_field_group_entity_view_display' => [
      'source_module' => 'fieldgroup',
      'destination_module' => 'field_group',
    ],
...

I think it's also possible to test it without the migate_upgrade module using drush?

Thx for the patch and the testing of it. I don't have a d6 site, so not able to test. But it's confirmed that it works, so committed to dev :)

The Field Group Migrate module migrates all CCK content groups from D6 to D8 Field groups but should only do this with standard content groups and not the multigroups (as mentioned by @askibinski in #4).
Minor change in the query() needed at the FieldGroup class, condition for group_type 'standard'.

Hello, thanks for the work everyone has done on this so far.
Please excuse me if this question seems "dumb" but where do I place the module? I'm assuming it should go in the /modules/contrib directory right? Shouldn't the plug-ins be registered in the migration configuration?

The code as it is doesn't appear to be seen by the migration module and or drupal_migration module?
When I migrate using the Drupal 6 site's database none of the fieldgroup "standard" groups get migrated. I'd like to help debug this and improve upon the group's work.

Before I provide any patches I'll continue to read up on the prerequisites on basic D8 concepts such as plugins, etc. I've searched around and haven't found documentation explicitly for writing plug-ins for migrations (that are not core migrations).
Am I just blind? Or does it not exist yet?

-- Update --
For those who are trying to understand how to get this to work do the following:
1) Apply Patch
https://www.drupal.org/files/issues/2611904-6.patch
* At the root of the /modules directory

2) Download and install migrate_upgrade
https://www.drupal.org/project/migrate_upgrade

3) Apply migrate definition
As stated in comment #5 https://www.drupal.org/node/2611904#comment-10557764
You'll need to modify the MigrateUpgradeForm.php in the migrate_upgrade module and include the form and view display definitions.

Then once you run the upgrade the field groups should be included.

I believe there should be a way to extend the MigrateUpgradeForm class and add to the $moduleUpgradePaths property. I would assume that in order to do that the migrate_upgrade module would need to employ the plugin design pattern.

Hi there, wondering if anyone was able to migrate field groups from D6 to D8 using drush and migrate tools?
I had the module enabled (8.x-3.x-beta) but in the metadata templates generated by drush migrate-upgrade --configure-only I can't see any reference to field groups... if not automatically generated, could you please point me how to get this migration working?

In here I see a reference to d6_field_instance_widget_settings template, but coulnd't figure out exactly how to add keys/values in migration yml templates.

Thanks!

Hello,

Facing no linked media from a D6 fieldgroup container for filefield, when I migrate D6 to D8.9.13.
Where can I find the migration yml file produce by migrate module to see what it done ?

Thanks
