This plugin merges arrays together.
@MigrateProcessPlugin( id = "merge" )
Use to merge several fields into one. In the following example, imagine a D7 node with a field_collections field and an image field that migrations were written for to make paragraph entities in D8. We would like to add those paragraph entities to the 'paragraphs_field'. Consider the following:
source: plugin: d7_node process: temp_body: plugin: iterator source: field_section process: target_id: plugin: migration migration: field_collection_field_section_to_paragraph source: value temp_images: plugin: iterator source: field_image process target_id: plugin: migration migration: image_entities_to_paragraph source: fid paragraphs_field: plugin: merge source:
- @temp_body
- @temp_images
destination: plugin: 'entity:node'
