Context: An existing web based app allows users to create presentations (front end - adobe flex) through their browsers & store them online in the web app (back end - asp.net, mysql)
Problem Descr: A new import feature is added which allows users to 'import' their existing powerpoint presentations into the web app (meaning the ppt is converted to swf and stored in the web app)
Question: What could be some technical tasks that the implementation of the 'import' feature could be broken down into?
PS: The questions might seem slightly broad, but seeking some thoughts on breaking the use case into 3-4 engineering tasks. Much appreciated!
