# About this guide
<a name="migration-guide-about"></a>

This guide describes how to upgrade a Conductor cluster consisting of AWS Elemental Conductor Live nodes and worker nodes (AWS Elemental Live and AWS Elemental Statmux). It describes how to perform an upgrade to a version in the range of 3.26.1 (2.26.1) to 3.26.5 (2.26.5) of the AWS Elemental software. 

This special guide exists because an upgrade to a version in that range requires that you install the RHEL 9 version of the Linux operating system. 

See [AWS Elemental Conductor Live Upgrade Guide](https://docs.aws.amazon.com/elemental-cl3/latest/upgradeguide/) if the following situations apply:
+ You are upgrading to a version earlier than 3.26.1.
+ You have migrated to a 3.26 version, and you now want to upgrade to a higher 3.26.x version to 3.27.x or higher.
