Automatic copy node from Drupal A to Drupal B Drupal A and B are different domain (example: drupal A: www.aaa.com and drupal B: www.bbb.com)but at the same server.
At Drupal A, there are lot of fields, but I only need to send date field value to Drupal B (Everytime when it update or add new content). Drupal B will get date value and display at the content page. May I know how to do that? 

I had tried Deploy (not working at all) 
How to add data from one Drupal site to other?

I had tried aggregate but I send everything to Drupal B.

I need help. Many thanks.

For far my current solution is:
At Drupal B: php code connect drupal A database and get the date vaule. Echo to display at the content page.
I would solve the problem with either of the following

1) Write a 5 minute custom php script that would show the node ids and data value and then update the nodes with data value in the second database with a simple update query on field_data_field_&lt;your-field-name&gt; table based on entity id.

2) Use services 3 module to expose your data and then import that field with put method with only the field you want.
