Yesterday I ordered The definitive Guide to Drupal from the dutch online site comcol.nl. Awesome delivery.
I have to read the monster 1047 pages but decided to cut it two pieces as that split version is allowed on my desk.
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.
