Upgrading Red Hat Enterprise Virtualization Manager to version 3.1 is performed using the rhevm-upgrade command. Virtualization hosts, and the virtual machines running upon them, will continue to operate independently while the Manager is being upgraded. Once the Manager upgrade is complete you will be able to upgrade your hosts, if you haven't already, to the latest versions of Red Hat Enterprise Linux and Red Hat Enterprise Virtualization Hypervisor.

Important

Refer to https://access.redhat.com/knowledge/articles/269333 for an up to date list of tips and considerations to be taken into account when upgrading to Red Hat Enterprise Virtualization 3.1.

Important

Users of Red Hat Enterprise Virtualization 2.2 must migrate to Red Hat Enterprise Virtualization 3.0 before attempting this upgrade. For information on migrating from Red Hat Enterprise Virtualization 2.2 to Red Hat Enterprise Virtualization 3.0, refer to https://access.redhat.com/knowledge/techbriefs/migrating-red-hat-enterprise-virtualization-manager-version-22-30.

Procedure 5.9. Upgrading to Red Hat Enterprise Virtualization Manager 3.1

Ensure that the system is subscribed to the required entitlements to receive Red Hat JBoss Enterprise Application Platform 6 packages. Red Hat JBoss Enterprise Application Platform 6 is a required dependency of Red Hat Enterprise Virtualization Manager 3.1.
Certificate-based Red Hat Network
The Red Hat JBoss Enterprise Application Platform 6 packages are provided by the Red Hat JBoss Enterprise Application Platform entitlement in certificate-based Red Hat Network.
Use the subscription-manager command to ensure that the system is subscribed to the Red Hat JBoss Enterprise Application Platform entitlement.

Ensure that the system is subscribed to the required channels and entitlements to receive Red Hat Enterprise Virtualization Manager 3.1 packages.
Certificate-based Red Hat Network
The Red Hat Enterprise Virtualization 3.1 packages are provided by the rhel-6-server-rhevm-3.1-rpms repository associated with the Red Hat Enterprise Virtualization entitlement. Use the subscription-manager command to enable the repository in your yum configuration. The subscription-manager command must be run while logged in as the root user.
```
# subscription-manager repos --enable=rhel-6-server-rhevm-3.1-rpms
```

Ensure that the system does not use any Red Hat Enterprise Virtualization Manager 3.0 packages by removing the Red Hat Enterprise Virtualization Manager 3.0 channels and entitlements.
Certificate-based Red Hat Network
Use the subscription-manager command to disable the Red Hat Enterprise Virtualization 3.0 repositories in your yum configuration.
```
# subscription-manager repos --disable=rhel-6-server-rhevm-3-rpms
```
```
# subscription-manager repos --disable=jb-eap-5-for-rhel-6-server-rpms
```
Red Hat Network Classic
Use the rhn-channel command, or the Red Hat Network Web Interface, to remove the Red Hat Enterprise Virtualization Manager (v.3.0 x86_64) channels.
```
# rhn-channel --remove --channel=rhel-6-server-rhevm-3
```
```
# rhn-channel --remove --channel=jbappplatform-5-x86_64-server-6-rpm
```
Update the base operating system.
```
# yum update
