What are the components for transitioning a Parent issue with Child and Linked Issues?

[Aston Kirsten Botes]

What components would I need, to create an automation rule that transitions the Parent issue to "Completed", when child issues as well as linked issues are transitioned to "Done" or "Completed".

Hi @Aston Kirsten Botes , this can be a little bit complicated depending on exactly your conditions, and I think you need to carefully understand when you want this to happen, and ensure that the proper conditions are in place such that you only do this action when desired. I will leave those details to you to figure out. I borrowed from the template library and simply added a condition for the linked issues in the image below. I think this should work for you. I would give it a try and play with it to test it out. Again please tweak to meet your exact requirements.
