Importing nodes with different field names from Drupal 6 to 7 I need to import certain nodes from a Drupal 6 site to a Drupal 7 one. I have a particular situation:


I need to import only nodes of a certain type
Node types have different names in the sites ("Question&amp;Answer" in the drupal 6 site, "Answers" in the drupal 7 one)
The 2 types have the same fields, but some fields have different names (The drupal 7 nodes have additional fields, but they are not required)
I need to put the id of the drupal 6 nodes in a field called "orig_id", the drupal 7 nodes need to have different IDs 
Nodes have 4 taxonomy relations: 2 use Hierarchical select, 1 (tags) can have new terms added when creating a new content (and the 2 sites have a different set of tags at the moment). 
Taxonomy vocabularies have different names, but (except for tags) contain the same terms.
Node Authors are the same in both sites, but they have different IDs. Importing authors references is not a must, so it can be skipped


I am fairly new to Drupal, i have tried searching for some import modules and/or articles about importing, but i can't find a guide that suits all my needs.
I have solved by checking which fields i needed, i made a table with those fields then made a custom boostrappable script to import them as new nodes
