How do I import applications from Online Filing into Online Filing 2.0?

After exporting the application from Online Filing, open the Administration tab in Online Filing 2.0, select Submission imports, then Import submission. You will find the imported item in "draft" status under Submissions. After opening it, you can move it to the desired status, to a folder or save it as a template.
