ScriptRunner has an built-in script that allows to clone existing project, which copy all instances (issues, schemes, etc.).
I need an option to copy only issues (in perfect scenario found by custom JQL search).
My usual routine is:
1. Create a project from a template
2. Copy (clone and move) all issues from "dull" project (issues are stages, epics and tasks) to a new one.
I want to automate step 2, which takes enormous amount of time and manual efforts.
