JIRA: Changing status between projects with link issues

[Carlos Faddul]

I would like to know how to do in the current situation, I have two or more projects, they all have equal status with each other. However each workflow has a rule, for example:

Project A
Open → To do → Done

Project B
Open ← To all
Review ← To all
Rating ← To all
To do ← To all
Done ← To all

Project C (communication between projects)
Open↔To Do↔ Done

In this case, project C; will be used as a way of monitoring the demands between the projects, without the users being assigned with project functions within the projects to which they are not part.

When a task is created in Project C (Open status) and is associated with a task in Project B (Open status), if one of the three modifies the To Do or Done status, the other status is updated to equal status.

I tried post-functions, however did not get the expected result.

Would anyone have any idea how to proceed?

I don't think this can be done with the native Jira code alone.  I believe this will require a plugin to jira that can transition linked issues when specific transitions are executed via a post function.   But which plugin to Jira you are using to do this will really determine how this will be configured.  From what I found searching I think that either the Jira Misc Workflow Extensions or Scriptrunner could be able to do this.

However there could be several other plugins that might be able to do this, with a different syntax.

But these add-ons in the case Jira Misc Workflow Extensions features somewhat "basic" functions of post-functions, while Scriptrunner costs around 1/4 of the value of each user, which ends up not compensating, since only I will use the plugin in a project only.

Why JQL and post-functions or triggers natively is not it possible then?
