Sorry. We haven't gone around to write offical documentation for export
yet. Once you have created a process in EPF, you can export it from just
using menu File->Export. And then selecting Microsoft Project in the
wizard. The wizard will guide you to selectzaA particular proces and the
configuration. This basically creates XML file which you could import into
Microsoft Project.
This gives you general idea but besides if you have any specific question
on export from EPF side, let us know. And we will try to answer that. Hope
it helps for now.
