Installing Drupal Commerce on a site upgraded from Drupal 6
In the last couple of weeks, we've had a few users ask questions pertaining to installing Drupal Commerce on a site updated from Drupal 6. The sites in question weren't Ubercart migrations, so there was no e-commerce data to bring forward. That's where you'd usually expect hangups to occur, which is why we're devoted significant time to the Commerce Migrate module to help transfer data from an Ubercart site into Drupal Commerce.
