<div dir="ltr"><div>ok, Itamar, thanks.<br><br>now I can understand how the things work.<br><br>but I have a question based on the fact that I have ovirt-engine on version 3.4 and DC and Cluster both are configured on version 3.3 : <br>
<br>- This means that I have "available" features on version 3.4 , but these features just will work when I update DC and Cluster to version 3.4 ? (this is what I understand, following Dafna Ron response)<br>
</div><div><br></div>so, to really obtain the benefits of the new version (3.4) I need to run the commands (yum update ovirt-engine-setup, engine-setup) and also increase the version of compatibility within the datacenter, cluster and host to the version 3.4<br>
<div><div><div><div><div><div><br><br>- and what I have if only update ovirt-engine to version 3.4 and not update dc, cluster neither hosts. <br></div><div><div><div><div class="gmail_extra">I realized changes on ovirt web admin interface, improvements on icons and maybe new fields.<br>

Hi,<br>
<br>
<br>
yesterday my ovirt was 3.3<br>
my datacenter and cluster (compatibility version) was aligned with ovirt<br>
3.3<br>
<br>
<br>
today my ovirt is now 3.4.<br>
and my datacenter and cluster (compatibility version) remains 3.3 (with<br>
the option enabled to change for 3.4)<br>
<br>
browsing the ovirt admin page I see 2 occurrences of ovirt version:<br>
datacenter tab = 3.3<br>
cluster tab =3.3<br>
<br>
<br>
<br>
I would like to understand what means all these versions, the same<br>
version for a lot of important things, and how my ovirt works/behaves<br>
using different versions.<br>
<br>
all my doubts together :<br>
What means datacenter in version 3.3(or lower version) when ovirt is 3.4 ?<br>
what means cluster in version 3.3 when ovirt is 3.4?<br>
what means change the "compatibility version" for datacenter?<br>
what means change the "compatibility version" for cluster?<br>

Gianluca replied with links for specific features.<br>
I'll reply on the general concept:<br>
- a host can be upgraded to a specific 3.x version. it can be in any<br>
3.y cluster which is <= 3.x<br>
once the host is upgraded, 3.x host-level features can be used<br>
- a cluster can be upgraded to 3.x once all active hosts in it are at<br>
least with 3.x.<br>
once the cluster is upgraded, 3.x cluster-level features can be used<br>
- a data cetner can be upgaeded to 3.x once all clusters in it are at<br>
least with 3.x<br>
once the DC is upgraded, 3.x DC-level features can be used<br>
<br>
i don't think we have it clearly documented per feture if it is host level, cluster level or DC level. when in doubt, ask...<br>
