Is there an upgrade path planed or will users stand in the rain / stuck like in some past i18n upgrades? I'd like to know if there will be an automatic process or if everyone need to develop upgrades on his own.

Yes, the plan is to provide an upgrade path to D8, which will likely be the only functionality implemented in the 8.x-2.x branch. Both translation models will be supported.

This won't happen until we are done with the D8 entity storage at least.

One question: In entity translation D7 I think all languages are saved in every revision, while in D8 "we write to the storage only field values that actually changed": #2562759-2: Nodes revision cannot be saved per translation.
So will the upgrade path be able to pull out the relevant changed translation for each revision in D7 or will just all revisions for all languages be imported into D8?

That means that only changed values are re-written, but they are always stored at least once per revision.

Has there been any progress on this issue? Is there going to be an upgrade path in the 8.x-2.x branch?

I'm using entity translation with field translation, i.e. language_content_type_{type} == 4.

#2225271: Migrate content type language settings from Drupal 6 & 7 seems to add support only for the legacy translation settings and not for Entity Translation with "field translation".
#2669964: Migrate Drupal 7 core node translations to Drupal 8 also seems to deal only with the legacy translation.

Any pointers as how to approach this in a new migration project?

Should this issue be moved to the Drupal core queue? I think that many migrations where d7 contrib functionality has been moved to d8 core are now handled in the core issue queue.

Unpostponing and moving to the core queue. I think There is nothing stopping this from happening other than people working on it :)

My colleague Jigar wrote some example i18n migrations, including one for D7 entity translation. The particularly interesting part is the custom source he used.

It's not quite a general solution—it's only for nodes. However, it definitely shows the major pieces:

  1. We need a way to determine whether a D7 bundle is entity-translated. This method works for nodes only, there's no general method for this—other migration sources will need different methods.
  2. As with other translatable sources, we need an extra ID field in getIds(), for language.
  3. We need to modify the query so it joins against the entity_translation table, and overrides some fields. Ideally this would go in a base class and/or trait for D7 migration sources, so they all could use it.
  4. We need to modify getFieldValues() so it supports a $language parameter, and then have prepareRow() use that.

Jigar also blogged about it now at -- can we turn that somehow into a more general solution in this issue? That would be great :)
