How do I migrate a multilingual site? I'm currently trying to migrate my Drupal 7 site, which has the Dutch language enabled, to Drupal 8. I have enabled the following modules as instructed in the docs: Configuration Translation, Content Translation, Interface Translation, Language. After running the migration, no nodes have been created on the Drupal 8 site. Moreover, the log contains lots of error messages similar to the ones underneath.


  Migration d7_node_complete:webform did not meet the requirements.
  Missing migrations language. requirements: language.
  
  Operation on Node complete (Webform) failed


Am I doing something wrong? How can I solve this?
It turned out that some of the migration processes were stuck after the first attempt. Here is how I solved the problem and completed the migration of my multilingual site:


Download and enable the Migrate Tools module and Drush 8
Run drush help to verify that new migration commands such as migrate-status and migrate-import are enabled
Run drush migrate-status and check the migration processes; all statusses should be Idle, but in my case some were stuck on Importing
Use migrate-stop to stop any running processes; according to the documentation, this ''cleanly stops a running operation''
Use migrate-reset-status to set the status of stopped processes back to Idle; according to the documentation, this ''sets a migration status to Idle if it's gotten stuck''
Continue the upgrade via the web browser or Drush
