Moving a .org site/collection to .net account

I was wondering if there was any way to export an Omkea site (or ideally, a collection) from the .org version to a .net account? I am currently working with a large class that is using Omeka for their final projects. As our quarter finishes, some students would like to continue using their collections and exhibits. Is there any way to export their materials from one version to the other? Thanks much!

I think that the most likely solution would be to use the OAI-PMH Repository (on current site) and Harvester (in plugins to move content from one site to another
