Description: 

As of #2409435: Upgrade path for Book 6.x and 7.x, the Drupal\book\Plugin\migrate\source\d6\Book Migrate source plugin (plugin ID d6_book) is deprecated and replaced by \Drupal\book\Plugin\migrate\source\Book (plugin ID book), which also works with Drupal 7 databases.

So:

  • If you have any migrations which are using the d6_book source plugin, you should use book instead.
  • If you have any classes extending Drupal\book\Plugin\migrate\source\d6\Book, they should be changed to extend \Drupal\book\Plugin\migrate\source\Book instead.

For example, a migration like this:

id: my_book_migration
label: 'Example Book migration'
source:
  plugin: d6_book

...should be changed to look like this:

id: my_book_migration
label: 'Example Book migration'
source:
  plugin: book
