Hi Xavier
The recommended best practice would be:
- Copy the requirement and point the copy at the new release, making changes as necessary.
- Keep the old requirement pointing at the old release, mark as obsolete
- If you need the test case status / traceability separate for each of the two requirement versions, you will also need to clone the test case and have the new requirement point to the new test case and the old requirement point to the old test case.
