Upgrading An Elastic Beanstalk Platform

Overview

Over time Amazon Web Services will send notices that an Elastic Beanstalk's platform will no longer be supported in the future. Eventually the environment will be tagged as "deprecated" in the EBS console.

There is an option within the EBS console under Environment > Platform to "Change" the platform. This leads to a dialog with a dropdown menu of the available platform options. I have run into situations where the available options are all older than the current platform and so are all deprecated.

In these cases it is necessary to create a new EBS application and new EBS environments within that application. These environments will have the latest platforms. It may be true that some upgrades may require a new application, but see if the desired platform is available in a new EBS environment first. It is usually necessary to update the configuration of those environments to suit the different layout of the updated platform.
