Sooo ... I've finally upgraded my own site. I thought it would be easy. A simple drupal site only using images. And yes I'm not reading READMEs that often. I trust drush somehow to handle this for me. But drush only sooth the 'pain'. This blog contains my bash script which does some staging from production onto my laptop where I update the site to the latest D6 then upgrade to D7. The script is generic enough to adapt for other upgrades.
