I need export all my projects for save the information. I need suport to do this.
Raise this with Atlassian support (we're end users here, we can't do anything with your ondemand system)
Actually, you can do it now without raising support ticket. See https://confluence.atlassian.com/display/AOD/Exporting+issues
