Hi Gianluca,<br>
<br>
currently we have:<br>
<br>
2 hosts (one is running also the oVirt Engine)<br>
1 DC<br>
We are only using NFS storage.<br>
<br>
No reports are used. But we have it integrated into our LDAP.<br>
<br>
Best regards<br>

<div bgcolor="#FFFFFF"> Hi oVirt List,<br>
<br>
I wanted to upgrade our oVirt 3.6.7 installation in the
next couple of days to oVirt 4.0.5.<br>
My hosts are running CentOS 7.2 currently. It is safe to
perform the upgrade also to CentOS 7.3? <br>
<br>
Is 4.0.5 also support this version of CentOS?<br>
<br>
It is correct that the upgrade to 4.0 is the same as
always?<br>
Just I need to install the new repositories?<br>
I guess I have to delete the old 3.6 repos or not?<br>

</div><div>In general this guide for RHEV should be of help for oVirt too:</div><div><a moz-do-not-send="true" href="https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/upgrade-guide/">https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/upgrade-guide/</a>
