Today I had the pleasure of launching a new Drupal 7 website into the Aegir hosting platform. However, I quickly discovered that migrating a Drupal 6 site and a Drupal 7 site, while similar, are really quite different.
The beginning
The website we were moving was built on a standard Drupal 7 installation on our development server. So the modules and themes were stored in the "sites/all/" directory and the files were stored in the "sites/default/files" directory.
