I want to split-off a project on an old Jira server (v6.4.5) and import it to a new server (v8.0.2). I tried using an xml backup file, with the intention of deleting all unwanted projects in the new server instance at some later time, but it says "The xml data you are trying to import is too old to be upgraded by this version of Jira."
It seems the only option left is to dump a csv file using some complex SQL command, which I guess has to be executed directly in the database interpreter psql (we are using PostgreSQL on both source and target servers).
It seems migration from many other tools is supported, but not from old Jira versions!
Is anyone aware of an easier way to do this?
BTW - both servers are (separate) stand-alone servers running in Linux.
