Open Nuendo 4.3 projects in Cubase AI 6


I asked a similar question before >here< but was regarding Cubase 6.5, I will buy the Cubase 7 in a couple of weeks but I really want to try my UR824 with Cubase AI6

So, as I said in the other topic I had a bunch of old projects in N4, Is there a way to pass them to Cubase AI ? or the only way will be a OMF file? Because I don’t have access to any computer with Nuendo 4 right now :frowning:
