Draft, not final. Be careful.

Note

I’m tested this procedure in my test lab with fresh oVirt 3.1 installation with following configuration:

oVirt 3.1 engine node (http://www.dreyou.org/ovirt/vdsm31/) , updated CentOS 6.4
2 hosts with vdsm (http://www.dreyou.org/ovirt/vdsm31/), updated CentOS 6.4
standalone NFS data storage for Storage/ISO/Export domains
oVirt was installed and confugured with NFS storage and 2 hosts, 1 virtual server created and started

oVirt 3.1 to 3.2 Update Procedure

To update ovirt 3.1 to version 3.2 you can follow next procedure:

If possible, backup engine, also you can backup all VM to export domain using oVirt console.
Add info about 3.2 repo to /etc/yum.repos.d/ovirt-dre.repo and

[vdsm32-dre]
name=Vdsm for oVirt 3.2 repo
baseurl=http://www.dreyou.org/ovirt/vdsm32/
http://www1.dreyou.org/ovirt/vdsm32/
enabled=1
gpgcheck=0

[ovirt32-dre]
name=oVirt 3.2 engine repo
baseurl=http://www.dreyou.org/ovirt/ovirt-engine32/
http://www1.dreyou.org/ovirt/ovirt-engine32/
enabled=1
gpgcheck=0

Check if 31 repo also ENABLED in /etc/yum.repos.d/ovirt-dre.repo

[vdsm31-dre]
name=Vdsm for oVirt 3.1 repo
baseurl=http://www.dreyou.org/ovirt/vdsm31/

[ovirt31-dre]

baseurl=http://www.dreyou.org/ovirt/ovirt-engine31/
http://www1.dreyou.org/ovirt/ovirt-engine31/
enabled=1
gpgcheck=0

On oVirt engine node execute engine-upgrade

engine-upgrade

If engine-upgrade found new version of ovirt-engine-setup you will be prompted to update this package, do it, then run engine-upgrade again:

yum update ovirt-engine-setup
  
engine-upgrade

engine-upgrade will stop oVirt engine, then back up database, then update packages and then start oVirt engine again.
Check if engine works correctly, if yes, now you can start to upgrade hosts.
Switch host to “Maintenance” mode.
Add info about 3.2 repo to /etc/yum.repos.d/ovirt-dre.repo

[vdsm32-dre]
name=Vdsm for oVirt 3.2 repo
baseurl=http://www.dreyou.org/ovirt/vdsm32/
