I'm trying to figure out how migrating content from a Drupal 7 site to a Drupal 8 site works. I managed to understand how to create a custom module to migrate nodes with regular fields to my new D8 site.
But I also have one content type where I use paragraphs. And I can't seem to find a well documented example on how to do this. I found some examples but they all seem to use different methods. This one seems like the most up to date. But how to make the code from #9 work?
field_paragraphs: plugin: sub_process source: field_source_paragraphs process: target_id: - plugin: migration_lookup migration: - paragraph_box - paragraph_grid - paragraph_text_embedded source: value - plugin: extract index: - 0 target_revision_id: - plugin: migration_lookup migration: - paragraph_box - paragraph_grid - paragraph_text_embedded source: value - plugin: extract index: - 0
field_source_paragraphs I understand. But what are these
paragraph_ items under migration? Is this where I set the paragraph bundles? And if not where do I set the paragraph bundles and there fields? So where do I begin? What are the right steps to take?
Thanks in advance
