Migrating for sale downloadable goods from VM1 to VM2 + st42_download

[nordmograph]

Hello

Thanks a lot for this great guide, I could test every steps successfully.
( http://forum.virtuemart.net/index.php?topic=102783.0)

I'm now getting closer to the migrating party day.
Only one thing is not clear to me and is not mentioned in this (not so complete) guide is how to migrate downloadable products.

Is this supported in any way?
I got st42_download plugin from extensions.virtuemart.net
But I could not get my files to be migrated and associated to respective products.

My customers have one year download so migrating to vm2 must keep their order history with respective downloads.

Any help/tip appreciated.
