Upgrading from Drupal to Drupal

This module has nothing to do with upgrading to Drupal 10.

The upgrade to D10 is just a code update, you don't have to do a migration see https://www.drupal.org/project/drupal/releases/10.0.0 → for more details.

I have a similar need too. I have an old Drupal 8 site and I am building a new Drupal 10 site with content types that are different from those of D8 site. So I can't upgrade the D8 site in place, but simply want to migrate the content only. Running the drush command `drush migrate-upgrade` on the D8 legacy database does not produce the migration config yaml files. I suppose I'll have to write the yml files manually. It's too bad that D7>D9 is very easy with this module, but D7>D10 is not.

I think this is currently out of scope for the module, which specifically says:

This module provides drush support for upgrading from Drupal 6 or 7 to Drupal 8.

That said, now that we can more clearly understand the scope I'm leaving it open for one of the maintainers to make the final decision.

There is https://www.drupal.org/project/migrate_drupal_d8/ → if you need between drupal migrate features.
