Issue Duplicator

With this GitHub Action, you can duplicate an issue with /duplicate issue comment. It creates a duplicated issue in the same repository with these copied properties:

• Title
• Body
• Assignees
• Labels
• Milestone
• GitHub projects (including their custom fields)

Note that the following properties are not copied from the original issue:

• Author
• Comments
• State (open or closed)
• Locked or not

For details, please read this blog post (in Japanese):
