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: https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/... <https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/upgrade-guide/>
HIH as a first insight, Gianluca
As the environment is simple I can try to simulate, probably next week, as an exercise, as I have to migrate a similar test environment then. I'll let you know. Plain ldap or freeipa or what? I will test with freeipa as shipped in CentOS 7.2 with updates (not yet upgraded to 7.3)
