How do I automatically trigger a status change on another issue JIRA?

[Marco Brundel]

I have a story with 3 (linked) tasks. When task 1 is Done I want automatic change the status of Task 2 to the state To Do and then when Task 2 is Done Task 3 to the state To Do
Is this possible with automation add-on?

This is the way I resolved it now.
When task 1 is transition to state DONE a automation rule change a customfield of the Story with the value Task 1 DONE,
and another automation rule change the state of task 2 to TO DO when in the story the custom field in the story is edit to "Task 1 DONE".

You would need to use the Branch rule / Related issues component. You will be able to find linked issues and perform actions on such issues.
