Hi noldo, yes well there are 2 different ways you can upgrade an educational version.

If you are no longer a student, you can get the v4 commercial version upgrade, it will work with a license from any previous version including either EDU or commercial.

If you are still a student then there will also be an EDU upgrade version available which will be at a lower cost than the regular commercial upgrade version. I do not sell the EDU versions directly myself though, they are purchased from a reseller like Studica. It will probably be a week or so before resellers will have the v4 EDU versions (both regular EDU license and EDU upgrade) set up on their web sites.
