Workbench Moderation Migrate

Workbench Moderation Migrate migrates Drupal 7 Workbench Moderation flows to Drupal 9 and alters node revision migrations to migrate them with the right moderation state.

Requirements

• Migrate Drupal (included in Drupal core)
• Node (soft dependency, included in Drupal core)
• Content Moderation (included in Drupal core)
• Applied core patch #1: #3200949-9: Non-default entity revisions are migrated as default revision because EntityContentComplete does not allows creating forward (and non-default) revisions
• Applied core patch #1: #3052115-32: Mark an entity as 'syncing' during a migration update

Core patch required for being able to update previously migrated records with
1. Core Migrate API with highwater property, or
2. Migrate Tools with its --update opt:

• #2329253-78: Allow the ChangedItem to skip updating the entity's "changed" timestamp when synchronizing (f.e. when migrating)

Usage

1. Enable this module and Migrate Drupal UI.
2. Visit /upgrade and configure your Drupal 7 source database.
3. Perform the upgrade!

Workbench Moderation Migrate module supports only complete node migrations (their plugin ID is d7_node_complete:<node_type>).

The migrate import command in Drush 10.4+ (or Migrate Tools) aren't building migration dependency graph^[1], they're running both the complete^[2] and deprecated^[3] node migrations, causing data integrity problems. Please keep this in mind if you don't use Drupal core's Migrate Drupal UI.

Footnotes:

• [1]: At the end this means they're executing the migrations in incorrect order and also executing migrations which should be skipped.
• [2]: Complete node migrations are the migrations with ID d7_node_complete:<node_type>.
• [3]: Deprecated node migrations are the migrations with IDs d7_node:<node_type>, d7_node_revision:<node_type> or d7_node_translation:<node_type>.
