I am a Jira administrator,there are five projects in my jira . Now my manager want to me divide a project to three projects according to different company,because three companies issue in one project ,so I think whether export one project to XML or Excel ,then I edit the XML or Exel ,divide a XML or Excel to three files ,finaly I import the three files into Jira become three projects .
I don't know whether the method of deal with this problem is the best ,if not ,please teach me better method.
If I use the method,the question is how to export a project to XML or EXCEL ?
