Drupal-to-Drupal data migration Taxonomy issues I'm wondering if there is something special I need to do within the UI when using Drupal-to-Drupal data migration to actually get taxonomy terms to port over with all my nodes. I get an error that reads


  No matching taxonomy term found for source value '144' in vocabulary Topics.


I've created first level terms and ported over each term correctly, but what is the special thing I need to do to actually map the terms with the nodes? I've mapped the TID and yet it still doesn't work. Is there something special Im missing?
Well, this is a couple years' old now, but thank you doodirock for tickling my memory on this. You need to configure that field's source_type value to 'tid'. I'm doing so in code, but I believe that you can set this in the UI. The code you need is this:

$this-&gt;addFieldMapping('field_news_categories:source_type')
  -&gt;defaultValue('tid');


In my UI view, this row appears like this:



Where 'tid' is the value input. 

As the documentation points out:


  source_type: If the option value is 'tid', then the incoming value is assumed to be a valid term ID in the destination Drupal instance. Otherwise, it is assumed to be a term name (the default behavior). Note that you'll want to set this to 'tid' if the mapping has a source migration (the sourceMigration() method is used on the mapping).
