# Working with RPM repository
<a name="migrate-topic-rpm-repository"></a>

AWS Elemental maintains an RPM repository for use with RHEL 9. The repository contains the following types of third-party packages:
+ Packages that are stored in the Red Hat BaseOS repository, and that are required to run AWS Elemental software.
+ Packages that are stored in the Red Hat AppStream repository, that aren't required but that you want to include.

For more information about the packages that you must obtain from the AWS Elemental RPM repository, and for instructions about configuring the repository, see the knowledge base article [ Advisory](https://us-east-1.console.aws.amazon.com/elemental-appliances-software/home?region=us-east-1#/viewknowledge/Advisory-AWS-Elemental-is-introducing-RHEL-9-2-support-for-Elemental-Live-Conductor-Live-and-Statmux-replacing-CentOS-7).
