Migrate Key Value

Migrate Key Value provides Drupal migrate source and destination plugins for the Drupal key-value store. This allows migrations to read from and write to any key-value collection, making it possible to migrate data that is not stored in regular entity or configuration storage.
Common use cases include:

• Migrating Pathauto states (pathauto_state:node, pathauto_state:taxonomy_term, etc.)
• Migrating any custom module data stored in the key-value store
• Remapping key-value entries where the key (e.g. an entity ID) changes between source and destination

Example:

id: migrate_my_collection
label: 'Migrate my key-value collection'
source:
  plugin: key_value
  collection: 'my_module.my_collection'
  key: migrate
process:
  name: name
  value: value
  collection:
    plugin: default_value
    default_value: 'my_module.my_collection'
destination:
  plugin: key_value
