Migrate address field I am currently searching for a example to migrate data into an address field in Drupal 8 without any luck for now.

Has someone a hint for me on how to map the fields?

I tried the following:

my.migrate.yml file:

'field_date_address/address_line1': date_tmp_address_address_line1
'field_date_address/locality': date_tmp_address_locality
'field_date_address/postal_code': date_tmp_address_postal_code


Callback:

$row-&gt;setSourceProperty('date_tmp_address_address_line1', 'Teststreet 18');
$row-&gt;setSourceProperty('date_tmp_address_locality', 'Test locallity');
$row-&gt;setSourceProperty('date_tmp_address_postal_code', '12345');
I was able to solve it :-)

This helped me:

It is important to map all addressfield subfields, otherwise it will not work.
