I have exported export.zip with JIRA 6.0 (with greenhopper add-on with 6.3.13.1. in its filename).
I then try to 'Restore' the export.zip with JIRA Server 7.2.3 (onsite installation) and get an error that JIRA Agile must be upgraded to version 6.7. I fail to do so as the JIRA Agile is an integral part of the application. Is there any documentation how to enable Restore/Import of the 6.0 file?
