Hi Gianluca,

currently we have:

2 hosts (one is running also the oVirt Engine)
1 DC
We are only using NFS storage.

No reports are used. But we have it integrated into our LDAP.

Best regards
Christoph

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

Best regards and thank you for your answers Christoph
Can you give more details, such as:
- how many hosts?
- how many DCs?
- how many Clusters?
- which kinds of storage domains in use (NFS, iSCSI, FC, ...)?
- currently using Hosted Engine? Planning to use it in upgraded 
environment?
- currently using reports and dwh and if so, currently using which 
database for them?
- other custom configuration aspects?
The more you give in advance the more other users can share about 
their experience.
In general this guide for RHEV should be of help for oVirt too:

HIH as a first insight,
Gianluca
