Currently I work with three Drupal 6 websites and I'm trying to find a guide or any advice on the best way to upgrade these sites to Drupal 7. These sites are module heavy and there is a process setup that imports customer and product information into the drupal database.
To my understanding, there isn't a very easy way to do this. I'm hoping I don't have to go through just setting up brand new sites - please tell me there is a way to transfer information.
Also, do any of you out there do contract work?
