How to migrate tables in nodes from D6 to D7, created with the tablefield module I am 90% done with my migration from D6 to D7. The last thing to figure out is how to map a table in certain nodes, created with the tablefield module in D6, into a table in D7, also created with tablefield. Just mapping the fields does not do the trick. 

$this-&gt;addFieldMapping('field_D7_table', 'field_D6_table');


With the above mapping there are no error messages, the table is just empty after the migration. I can see that the data is stored in serialized form in the legacy database. Can anyone point me in the right direction?
Tablefield does not currently include migration support - there is a patch to add it at https://www.drupal.org/node/2317245. If you try out the patch and report on your results there, you may help move it forward.
