How to ensure Parent User Story moves to Done only if all Child Subtask are Done

[Swift India]

Hi Team

I am creating a setup Epic -> User Story -> Sub Task(s). I want to ensure the User Stories are moved from To Do to In Progress followed with Done only if the Child Sub Task has moved from To Do to Done. By Default I am able to move the User Story with Sub Task in To Do Status moved to Done.  Ideally the Parent Must be moved to Done only if all its child are Done - Please help

Welcome to the Community!

I'm very fond of editing the workflow and adding the "condition" called "Sub-Task Blocking Condition" (probably because it's been in Jira as long as sub-tasks have).

This condition lets you select a list of status that all the sub-tasks must be in before their parent can be moved through the transition.

It's not as limited as just "can't move issue to done when sub-tasks not already closed,", you can do stuff like "don't allow issue to go into testing until all sub-tasks are in testing or beyond"
