Based on what PTC says about 2000i^2, the only way to do it is to export neutral files from the Student Edition then import the neutral files into the commercial version. I've been working the issue and I will advise what I find. It is not clear as to what is lost in the process.
Oh, you said the Educational Edition! That's different from the Student Edition. I don't know but I thought I heard someone say that there was IGES compatiblity between them but you'd have to confirm that for yourself.
I havn't tried it my self but I Know some people have done it by creating a UDF of the whole model (UDF = user defined feature) from one product and then reading the UDF into an empty part file in the other version of Pro/E.
It seem UDFs can be hapily exchanged between student and comercial versions of Pro/E
