Update the Custom Date field in Sub-Task if the Parent Custom Date Field is Updated

Bunny

Hi,
I am creating a sub-task from the script-Post Function that creates a sub-task on the transition.

am copying all the fields from parent task to sub-task

When I update a Custom Date Field in the Parent task, It should get carried to the subtask as well.

It was resolved

and I want to extend the functionality to the linked issues if that's possible.

So your main question is regarding updating linked issues if the customfield is updated.

You would need to write a script listener on issue updated events for that. 
Which would pick up changes on the customfield and propagate them onto the linked issues.

But issue links don't have relationship of parent/child. 
So if you update the customfield from either side of the issue link, the other issue would be updated. 
Or you would have to make a logic that suits your need and code it with script listener.
