The project A I am referring to is an old project which has to be retired soon. All of its issues need to be migrated to Project B.
As part of this migration:
1. Project A issues are marked as "Retired" in the status
2. New issues are created in Project B
3. For future traceability, Project A issues are linked to these new issues in Project B under "is replaced by".
I am looking out for a jql filter to search for Project A issues that have not gone through the above process so that I can export them, feed them in a new csv template and bulk import them in Project B all at once.
Please suggest if there are any alternate better options?
