Migrating a project from a demo installation

How can I import a project from the demo installation on a local computer?
I installed the licensed SC on another server but I had some work during the demo period. The export of projects under the demo is off.

Generate another license key.
Use key on the demo
Export your projects
Generate another key again
Use key on your scriptcase.

Thank you , this was a good advise. BTW , when migrating projects , do not forget any non standard templates used. They are not taken care of by the export/import functionalities.
