Import File Not Being Displayed
Problem: If after copying your complete project import file over from the Source instance to the Target instance, it is not displayed in the Project File box on the import screen then you should follow the steps below in order to resolve this issue.
Ensure the file is placed under
<JiraHomeDirectory>/import/projectconfiguratoron the Target instance.
Ensure the permissions for the import file are set so it is owned by the same operating system user and group Jira is running under.
Refresh the project import page after making these changes to ensure that the import file is displayed inside of the Project File box on the import screen.
