How do I update my Drupal Core to 6.22 when using the Mercury 1.1 stack. I've been running Mecury on EC2 for about 6 months and everything has been great, but recently Drupal released Core patches for 6.20 that have security updates. I researched updating Pressflow using Bazaar, but I don't know if that's what I need to do and I don't want to hose my site.
Anyone updated to Drupal Core 6.22 that is using the Mecury 1.1/Pressflow setup?
