Question

Should I disable sub-tasks to use Structure?

Answer

Not necessarily. While Structure can be a good replacement for sub-tasks, they can be used in parallel — for example, if you want to try Structure on a single project without affecting other Jira users.

Structure treats sub-tasks as any other issues. If you're using Automation, you can also include a Sub-Tasks Extender to automatically add Jira sub-tasks beneath their parent issues.
