Scrumwise can export its whole data as XML. This contains lots of data including Projects, Backlog, Sprints, Tasks, Team Members, etc. It can also export Tasks as CSV.
GreenHopper can import Projects in various formats (but not XML).
I'd like to transfer as much as possible between Scrumwise and GreenHopper. I'm thinking of extracting the Projects node from the XML, converting to JSON, and importing that. Right now GreenHopper rejects the data right from the start.
Is there a reference to the data schema used in GreenHopper? I'd like to transfer more than just the Project, but all its associated data.
