Paragraphs migration example?

++ on #25 thank you Santhosh and cmeh.

As an alternative to Paragraphs, in case a more basic solution might work, migrating nested multivalue data into Custom Field → is easy. A structure like this:

"hyperlink":
  [
    {
      "linkurl_source": "https://drupal.org",
      "linktext_source": "Drupal"
    },
    {
      "linkurl_source": "https://gitlab.com/",
      "linktext_source": "GitLab"
    }
  ]

... can be mapped with this:

fields:
    -
      name: hyperlink
      selector: hyperlink
[...]
process:
  field_hyperlink:
    plugin: sub_process
    source: hyperlink
    process:
      linkurl: linkurl_source
      linktext: linktext_source

From Migrate multivalue fields into unlimited Custom Fields field → .

I am working on a Drupal 10 to Drupal 10 migration. All the examples here did not help. Looks like they are related to Drupal 7.

My solution was an own migrate process plugin. You can find it here: https://git.drupalcode.org/project/sites_migrator/-/blob/1.0.x/src/Plugi...

The plugin must be implemented into the process like this:

  field_paragraphs:
    plugin: paragraphs_sub_process
    source: field_paragraphs
    migration:
      - wg_paragraph_media_text
    process:
      target_id: '0'
      target_revision_id: '1'

I hope this example helps somebody.

#35 works fine, but made a slight adjustment for multiple migrate sources 🐛 ParagraphsSubProcess plugin does not merge paragraph items when using += operator Active
