At BitNami, we strive to always provide you with the most up-to-date versions of all of the applications and supporting software that we package. In connection with this, we are constantly publishing updated BitNami Stacks. In fact, just this month-to-date, we have already published over 20 BitNami Stack updates!
One of the many benefits of running BitNami in the cloud is that you can easily clone servers to apply updates before promoting an updated server into production. This is made even easier with BitNami Cloud Hosting, our platform for deploying and managing web apps in the cloud. We have put together a how-to guide to walk you through the process of upgrading your BitNami instance from one AMI version to another, which will work for both AMIs launched directly through Amazon as well as those launched with BitNami Cloud Hosting. In addition to this general guide, we have also put together tutorials for upgrading servers running BitNami Wordpress, Joomla! and Drupal on the Amazon cloud.
