Problem/Motivation

Note that, as of 8.8.x, modules can declare their Drupal 8 (or 9) upgrade status ( changelog → , issue #2936365: Migrate UI - allow modules to declare the state of their migrations → ). Since there is no data to migrate from diff-7.x-2.x, diff-6.x-2.x, and diff-6.x-1.x, we should mark those migrations as "finished".

As a site owner migrating my site from Drupal 7 running diff-7.x-3.x to Drupal 8 or 9 running diff-8.x-1.x, I want to migrate configuration from diff, so that my Drupal 8/9 site has the same behavior as my Drupal 7 site.

It appears that 7.x-3.x stores the following data:

  1. Global variables:
    1. - migrations exist as of #5
    2. - migrations exist as of #5
    3. - done since there is no corresponding 8.x-1.x features/settings
    4. - migrations exist as of #5
    5. - done since there is no corresponding 8.x-1.x features/settings
  2. For node and user entities, the following variables:
    1. - done since there is no corresponding 8.x-1.x features/settings
    2. - done since there is no corresponding 8.x-1.x features/settings
    3. - done since there is no corresponding 8.x-1.x features/settings
    4. - done since there is no corresponding 8.x-1.x features/settings
  3. For file fields, a diff_file_field_file_default_options variable that contains the following data:
    1. show_header (boolean)
    2. show_id (boolean)
    3. compare_alt_field (boolean)
    4. compare_title_field (boolean)
    5. property_separator(string)
    6. markdown (string)
    7. line_counter (string)
  4. For image fields, a diff_file_field_file_default_options variable that contains the following data:
    1. show_header (boolean)
    2. show_id (boolean)
    3. compare_description_field (boolean)
    4. compare_display_field (boolean)
    5. property_separator(string)
    6. markdown (string)
    7. line_counter (string)
  5. For each list field type, a diff_list_field_{$fieldType}_default_options variable that contains the following data:
    1. show_header (boolean)
    2. compare (string)
    3. markdown (string)
    4. line_counter (string)
  6. For each text field type, a diff_text_field_{$fieldType}_default_options variable that contains the following data:
    1. show_header (boolean)
    2. compare_format (boolean)
    3. markdown (string)
    4. line_counter (string)
  7. For taxonomy [term reference] fields, a diff_taxonomy_field_taxonomy_term_reference_default_options variable that contains the following data:
    1. show_header (boolean)
    2. show_id (boolean)
    3. sort (string)
    4. markdown (string)
    5. line_counter (string)
  8. For each remaining field type, a diff_{$d7Module}_field_{$fieldType}_default_options variable that contains the following data:
    1. show_header
    2. markdown
    3. line_counter

Proposed resolution

Add migrations.

Declare the finished upgrade path from D6 by creating a migrations/state/diff.migrate_drupal.yml and populating it appropriately.
