I need to migrate an ordinary D7 multi-value long text field 'body' into D8 paragraphs . As paragraphs seem to be a reference, the migration will probably be more complex than just direct field mapping. Moreover, my target paragraphs include multiple fields, not only the text body but a title as well. Any idea or link how to accomplish this task?
Paragraphs are entities in and of themselves - it's most straightforward to migrate the paragraphs separately, then populate the reference to the migrated paragraphs within the "parent" node migration.
