Fedora Atomic Host installations use the [https://rpm-ostree.readthedocs.org/en/latest/ rpm-ostree deployment method], where packages are assembled on the Fedora release engineering side and delivered as atomic units, rather than the yum/DNF method of client side assembly.  Consequently, they do not use the [[DNF system upgrade]] mechanism which is used to upgrade between Fedora releases for other Fedora installations. Instead, use the procedure described here.
This article applies to Fedora Atomic Host (though there is also a [https://pagure.io/workstation-ostree-config/ Silverblue/Atomic Workstation]).  For "classic" Fedora Workstation and Server, see [[DNF system upgrade]].


{{admon/note|One OSTree repository per release|It's crucial to note that at the moment, Fedora uses separate OSTree repositories for each major release.  This makes switching between versions more painful.  For more information, see [https://fedorahosted.org/rel-eng/ticket/6125 this ticket].}}

Let's assume you're upgrading from Fedora {{FedoraVersionNumber|previous}} to {{FedoraVersionNumber|current}}. First, you'll need to add a remote for the new major version:
Upgrading from [http://www.projectatomic.io/blog/2018/10/fedora-atomic-28-to-29-upgrade/ Fedora Atomic Host 28 to 29].


ostree remote add fedora-{{FedoraVersionNumber|current}} --set=gpg-verify=false https://dl.fedoraproject.org/pub/fedora/linux/atomic/{{FedoraVersionNumber|current}}
And [http://www.projectatomic.io/blog/2018/05/fedora-atomic-27-to-28-upgrade/ Fedora Atomic Host 27 to 28].


Then, rebase to it:
And [http://www.projectatomic.io/blog/2017/11/fedora-atomic-26-to-27-upgrade/ Fedora Atomic Host 26 to 27].
 
rpm-ostree rebase fedora-{{FedoraVersionNumber|current}}:fedora-atomic/f{{FedoraVersionNumber|current}}/x86_64/docker-host
 
Like any other rpm-ostree update, this is staged for the next reboot, so to finally apply the update:
 
systemctl reboot
 
That should be all!
