It will all depend on Advantage 3's import capabilities. I don't know a whole lot about it...but one of the big "advantages" of Advantage is it's wide-range of export/import capabilities. At least that was always my impression of it.
Do you have a way to find out what file formats Advantage3 will accept for import?
I asked someone with indirect knowledge on the project, who said that it is XML with an interface using PDI. I am a beginner so I have limted info.
