How to migrate drupal6 ubercart to D7 commerce I have a website in D6, and ubercart is used now i want to upgrade the site to D7 but with commerce. How can it be done?
You probably want to look at Commerce Migrate together with Commerce Migrate Übercart that respectively understand how to create Commerce content and read Übercart content.

Commerce Guys already wrote two blogposts, Part 1, and Part 2, on the difference between the two.
