Hi, I have a team-managed project on Jira (Cloud). This board has gone live and there are issues created previously using the issue type named System Name. I have created another issue type named New Form. I want to "merge" the New Form into the System Name so that when users create a new issue, it will be the New Form. But I also want the data for the previously created issues in the System Name to retain and not be overridden by the New Form. Is this possible?
