Can I use automation rules to update the assignee?

[Geoffrey Cooper]

Jira Cloud. Multiple project service desks. Relatively new to the automation section. I'm trying to figure out an automation rule that will set the the Assignee to unassigned when an issues is moved from one service desk project to another. Is this a field that can be modified with custom automation rules?

Hi Geoffrey,

Welcome to Atlassian Community!

It’s possible to set an assignee to unassigned when moving an issue using an add-on, since on Service Desk built-in automation there is no trigger for that.

You can use the add-on Automation for Jira (if you move less than 300 issues a month, you can use the free version). 

Regards,
Angélica

Unfortunately, an add-on is not going to be an option for me. Is there a way through Jira automation?

Jira automation does not have a trigger to run when an issue is moved, that's why it would be necessary to use an add-on, otherwise, the best option would be manually set the issue as unassigned before moving.
