I am working to move one of our departments from a Team-Managed Jira software project to a Company-Managed Jira Service Management project. I am running into an odd issue where the new projects board (Project ABC) has all of the issues from the old project (Project DCE), I know this because each issue has the key from the old project (DCE-2554).
I've looked extensively to see if there's a setting that somehow connects the new projects board to the old project issues, but I don't see anything that allows me to change the location. Any help on this would be great. If there's any clarifying I need to do, please let me know.
