I think you might be in the wrong place - this is for Atlassian applications, and I don't think any of them have a "parent portal".
I do know their applications are used increasingly to support the development and support of educational software (Moodle is the one my closest friend has pointed out to me - the Moodle developers use the Atlassian suite to help them track and maintain Moodle), but I suspect you've followed the wrong "help" link. If not, could you explain which Atlassian app it is?
