How can I copy Due Date into a customfield in existing issues?

[Begoña Bonet]

In existing issues I need to copy the Due Date value in a customfield. 

When both, the source and target field are customfields I always use the Built-in Script "Copy Customfield values" but, in this case the souirce field isn't a customfield and I can't use this script.

Any idea?

Thanks

Hello there,

The option Copy Field Value on the plugin JIRA Command Line Interface might work for you.

Thanks and regards,

How about the post-function "Copy value from field to field"?

Finally I've solved this modifying the flows and including a post-fuction using "Copy value from field to field".

Thanks

@Begoña Bonet  Can you share with me the steps. I need to copy my due date field values to a custom field. 

And I like to do by your method  "Copy value from field to field".
