Problem/Motivation

We want to provide an upgrade path from the Drupal 7 feeds module to Drupal 8.

Proposed resolution

Implement migrations from:

  • D7 feed importers to D8 Feed types
  • D7 feeds to D8 Feeds
  • D7 feed items records to D8 feed item fields (the d7_node migration will already have migrated the nodes)

Remaining tasks

We need to support the following parsers:

  • FeedsCSVParser
  • FeedsSyndicationParser
  • FeedsOPMLParser
  • FeedsSimplePieParser
  • FeedsSitemapParser

We need to support the following processors:

  • FeedsNodeProcessor
  • FeedsUserProcessor
  • FeedsTermProcessor

The field mappings also need to figure out if the target field is a reference field, to use 'target_id' instead of 'value'.

The D7 generic config (variables) also needs to be migrated into D8 config.

This is just a WIP that I want to share for now. There's a few things that already work, and others that fail miserably.

No problem. It did work for me (mostly), but now I need that #2799225: The "hidden" plugin does not exist: Drupal\Component\Plugin\Exception\PluginNotFoundException: to be fixed...

Slightly improved version that detects if the destination field is an entity reference field.

Hello and thank you for working on this patch, I'm trying to upgrade a site with a lot of feeds importers from D7 to D11.
I managed to install the patch using composer but on the third step of migration I get the following wrror:

The website encountered an unexpected error. Try again later.

Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "plugin.manager.migrate.cckfield". Did you mean one of these: "plugin.manager.migrate.source", "plugin.manager.migration", "plugin.manager.image.effect", "plugin.manager.migrate.process", "plugin.manager.migrate.destination", "plugin.manager.migrate.id_map", "plugin.manager.migrate.field", "plugin.manager.views.field"? in Drupal\Component\DependencyInjection\Container->get() (line 157 of core/lib/Drupal/Component/DependencyInjection/Container.php).
