Problem/Motivation

In #2842222: D7 Plain text fields incorrectly migrated to D8 as Text (formatted) → , we decided to not migrate text fields with conflicting text formats. This also means that there are data which is not migrated into the destination site – and it is very visible if your migrated node misses its (imho) most important body field's data.

As a user migrating from Drupal 7 to Drupal 9, I don't expect data loss in regards of core-provided fields.

Proposed resolution

Migrate even those text fields (and the data they store) which have conflicting text processing settings (on their field instance level).

My ideas:

  1. Migrate text fields conflicting text_processing setting as formatter text fields, but map their filter to plain_text.

    Pros:

    • Easy to implement.
    • Only the field migrate plugin should be modified.
    • The migrated data is still rendered the same as on the Drupal 7 source instance.
  2. Create separate field storages for text fields with conflicting text_processing setting: one for the plain text fields, and one for the formatted ones.

    Pros:

    • Data storage can be closer to Drupal 8|9 standards.

    Cons:

    • Less likely to be committed to core (ever) – because of unresolvable BC impacts.
    • The migrate source plugin should be modified – including also the data.
    • I don't (yet) know how, but every field_name destination plugin should use a lookup for getting the destination field name.

This issue/patch implement idea 1.
