The migration tool is bugged, no price, VAT ... imported.
Downloadable products arn't imported, and it even seems that you have to pay an extension to have downloadble products, it was free in the VM 1.1. The front end crashes very often (DB error).
So, I will look for other e-commerce solutions...
Re Migration tool!
May I explain, the migration helps many people move from different versions of Joomla, as well as different versions of VirtueMart, which is pretty slick Considering the number of uses people have found for VirtueMart, buggy is a word that is different to many many people, and is caused by different issues, so the word used in this example is very broad in meaning.
Please consider this, many people are using VM2, so maybe there are some local issues you have that are causing the problem of the front end of your site to crash, have you checked the storage URL of your downloads?, please try and revisit the problem, by setting up a standard install and ensuring everything works, then try using the migration tools.
