Is there a way to programmatically add sub-tasks to existing issues?

[Pete P]

I have modified my workflow so that (4) subtasks are automatically added upon creation of an issue. 

Example:

• Web Team deploy to QAT
• DBA Team deploy to QAT
• Web Team deploy to UAT
• DBA Team deploy to UAT

How can I programmatically add these 4 sub-tasks to my existing 1000+ issues in the backlog?  I used the Bob Swift Atlassian Add-ons - Create on Transition to add them on issue creation.

Here's a thought ... use the bulk change functionality to transition those issues, using a specially-crafted transition that it available to all statuses and moves the issue from its status back to itself (so as not to change the status), and use a post function to create the subtasks. Remove the transition when you're done.

I'd certainly do this in a test environment first on a small number of issues.

Thanks Payne, for the quick reply.  That is a good suggestion, I will give it some thought and try to implement.  I'll post back here once I am able to test it out.
