Question:

Can I Move Existing Linked or Associated JIRA Issues to Other Projects?

Answer:

There is no problem if moving the linked or associated JIRA issue to another Project. The important thing is the target Project must have the same Mapping Scheme with the original Project.

To associate created Mapping Scheme go to Administration > Project and select the project.

Then select Project Mappings.
